    My indoor cats and my feral have been eating Iams 10 years now. Recently I purchased two large bags and my indoor cats are very sick vomiting violently severe diarrhea. They became severely dehydrated. I really did not know what was happening. I went outside to check on the feral cats and I was stunned that not any of them would eat the food so that is when I realized it is the food. Seriously my cat Lambie almost died. He is on antibiotics and lots of fluid. All my poor sweet animals have lost weight. I am truly worried because they have matted coats from not grooming themselves. I called the very reputable company I use to purchase the food and I was told to stop using it immediately so I did. So please everyone be very cautious giving your furry love bug this food.

    My cat was on this brand for many years. She was a rescue cat, always small and always kind of rough coated with a kind of dandruff problem. I was told years ago Iams was a good brand so I stuck with it and she ate it well. Last summer quite suddenly she started vomiting. Once a every few days at first then it quickly progressed to daily then multiple times a day. I grew quite alarmed at that point and knew this wasn't just from hairballs.

    Before I booked a vet appointment I decided to go online and consult Mr. Google and I found all these reviews. Hum, could this be? So I threw out the Iams, went to the pet store and bought the best limited ingredient food they had. I figured for it to be a real test it needed to be as limited ingredient as possible. Lo and behold she NEVER vomited again, not once. Yes it's more expensive but honestly not by a huge amount because she eats less of it and that little rough cat has turned round and full and her coat is silky and lush. What a difference. She also has turned into a kitten again..playing and running around like crazy. AVOID IAMS!

    I was away for a few days and I had my kids buy some cat food for our cats. I told them to buy IAMS but they went to Walmart to get it. My cats will not eat it and the pellets are different shapes and colors than the last bag I bought at a grocery store. With the other reviews I have read I am now very concerned for my cats. I will be contacting the company tomorrow and expecting to get my money back.

    We have tried the Orange bag IAMS™ PROACTIVE HEALTH™ INDOOR WEIGHT & HAIRBALL CARE. PROACTIVE HEALTH™ food for our four cats and they puke every time we have tried them on it. We have only used it when their brand is out of stock, but every time it has made them all get very sick. It seems like this is a common problem.

    September 9th of 2019 I was given an 8 week old kitten from a friend. She was in good health (even though she was a little small due to being the runt) and when I took her to the vet at 9 weeks they said she was perfectly healthy. My vet recommended that I switch to another food from what I was feeding her and one of the options was Iams Proactive Kitten Food. I switched her foods how I was supposed to, gradually, and she seemed okay for a few days. Until I noticed that she was throwing up every time she ate and wouldn’t touch her food anymore.

    I took her to the vet as soon as I could and she was about 11 weeks, they told me she was probably throwing up because I switched her food too fast and that it should subside and she seemed in good health. I believed them but within a week and a half later she passed away. I later found this thread and I wholeheartedly believe it was the Iams kitten food that caused her untimely death. Rest In Paradise my sweet Aurora.

    My family has two cats, both 12 years old. We have been feeding them Iams since they were kittens and they have never had a problem. As they have grown up, we have switched their Iams brand of food to match their age/stage of life, again, experiencing no problems. Unfortunately, that is no longer the case. Our cats have, both, been experiencing diarrhea and have been vomiting not long after eating the Iams Mature Senior food. Our smallest cat got REALLY sick a few months back, necessitating a trip to the vet. All tests run on both cats revealed negative results. We're beginning to believe it's the food, because they are both experiencing frequent diarrhea and vomiting, not long after eating. We've talked about changing their food to another brand, especially after reading the comments everyone else has posted on this forum. I hope Iams gets the message because it absolutely heartbreaking to see our precious pets get so sick after eating.

    I have a 3 year old neutered male cat who was recently diagnosed with FIC. The be recommended I change his food to one of the urinary tract health cat foods. I started with Purina One urinary tract health and he hated it. He was barely eating so I decided to try this Iams food. He loved it, but later that same day he started having diarrhea. I thought it was just from switching foods again. The next day he was still eating but the diarrhea persisted and he started becoming lethargic and dehydrated. I will never feed this kind of food to my cat again. I'm also so glad that other people wrote reviews on here about this food. It has probably saved his life.

    I have been buying Iams a long time for my 2 cats. For starters does everyone know that Iams cat food brand is owned.by the Mars Candy Company. Just found that out after doing a little research. Anytime I buy. Iams cat food from Walmart my cats get sick. Or they won't eat it. And the Iams at Walmart the dry food orange bag anytime I bought that at Walmart. It's a lot darker the morsels then when I buy same thing in other places. It's a lot lighter. Seems like Walmart get the low grade Iams. Lol I will no longer buy Iams. Their product is terrible and scary seeing my cat get sick from it.

    I'm reporting this in the hopes that Iams pet food is investigated. In fact, I demand it. I think it's very important that we divulge what state we're from, and also where we bought our Iams Cat Food. We live in Iowa and we've always bought Iams Proactive Health cat food at WalMart. In August, 2019, our much loved large breed cat stopped eating his Iams Proactive Health cat food. He's been eating Iams since the day we brought him home as a kitten.

    Beginning in early August, he began acting like he was quite ill. I would feed him his Iams, but he would just sit and stare at his food bowl. He was vomiting green bile daily. He was drinking more water than usual. He stopped grooming himself and his beautiful coat looked horrible. Because he wasn't grooming himself he developed severe matting in his fur. He was lethargic, and he wasn't the social cat we were used to. Instead of being the energetic, sociable cat he once was, he would hide underneath our bed all day, and all night. The light in his eyes was gone.

    He weighed well over 15 pounds, before he stopped eating, but when the veterinarian saw him, he'd lost five pounds! What's interesting is that our cat would not eat his Iams, but he was very interested in eating the dog's food. The veterinarian thought that was rather odd, and so did we. That said, dog food is not good for felines.

    The veterinarian kept him for several hours and said she'd call us when she was done doing blood work and examining him. She phoned us two hours later, and we went in to hear news that completely shattered our world. She said all four veterinarians in the pet clinic were in agreement that our cat has B-Cell Lymphoma. We asked if his blood tests were normal, and they were. But she said all of his symptoms were spot on for B-Cell Lymphoma. B-Cell Lymphoma is a blood cancer that develops in the lymph nodes. She added that his lymph nodes felt normal. But again, noted that it was odd that he was hungry for dog food.

    She referred us to an emergency clinic for an ultrasound, a bone marrow biopsy, and chemotherapy.

    This is a breakdown of the cost: Office visit : $125, Ultrasound : 426, Bone Marrow Biopsy : $2,231, Chemotherapy : $3,000 to $5,000. Because he wanted to eat dog food, on a hunch, I bought a different brand of food; Little Friskies Indoor Delight. He started eating like there was no tomorrow. I waited to report this because I wanted to be absolutely certain there was something wrong with the Iams food.

    To date, 9/28/19, he has gained all of his weight back. He's grooming himself, he's not vomited once, and he's back to his normal energetic self. Please, PLEASE, PLEASE do some investigating into Iams Cat Food! Our little Papillon dog later developed similar symptoms while eating Iams Proactive Health food. I will post about this later.

    I am a TICA and CFA registered breeder and I recently switched jobs so my budget was a little tighter in between pay checks. I went out and purchased 5 bags of Iams dry cat food both the orange and turquoise bags from Walmart to tide my cats over for a few weeks while my pay is worked out. My cats did ok the first few days and then started vomiting projectile piles of cat food. I have several zones where my cats are housed and any new cats or cats set to leave are quarantined as well. Being that some of my cats do not ever interact with one another (studs for example) and the fact that there was vomit from each cat who ate the food I know there is something going on with the food itself. I will also be contacting Iams to try to be refunded for this as my cats cannot eat it obviously. One of my cats threw up so many times I have had to administer subcutaneous fluids for him. Please look into what is happening with your food!

    We've been giving our 2.5-year old cat IAMS Hairball Care Adult Cat Dry Food mixed with wet food for two years. 4 weeks ago, he started vomiting on a daily basis. First, he was repeating to eat and vomit and he started eating less and less every day while waiting for the appointment with our vet. It looked like vomiting and not eating made his sick worse. Only he was eating was his favorite treats at the end and one day he completely stopped eating and drinking water.

    I knew if a cat does not eat even for 24 hours it could damage their organs so on the second day without eating, we could no longer wait the appointment and took him to an emergency. He has got the IV and got a x-ray, an ultrasound, and a blood test but the vet could not figure out why he was not eating and said he is a very healthy cat based on all test results and there is no reason that he is refusing to eat.

    We took him home after two days in the emergency and he was given medications for anti-acid/vomiting and an appetite stimulant. Next day of the emergency, he started eating boiled chicken breast. It was less than 1 ounce at each meal but it was better nothing. We continued daily medications and syringe-feeding to force him to eat twice. He lost 4 lb in 4 weeks and he got so skinny so we were very glad to see him eating more and more without throwing up day by day and his grown appetite. After about a week of feeding chicken breast, we decided to try feeding him his regular wet food little by little mixing with chicken breast and he was eating them fine without getting sick until he was given dry food.

    After eating just wet food for a few days, we mixed a few pieces of dry food with wet food in the morning and we increased dry food little by little on each meal. At the night of the second day we gave him dry food, he vomited all food he ate all over in our bed room. Then I decided to research about IAMS food and found these reviews. I should have done it earlier but after I saw all reviews there was no doubt the bag of dry food go to our garbage.

    I have been feeding my 2 cats Iams dry cat food for years. About 4 weeks ago my 10 yr old cat started vomiting once or twice a day. I got her to the vet who gave her a shot to make her stop vomiting and put her on an antibiotic in case she had a bacterial infection that was causing her to vomit. I leave the cat food out for my cats at all times. Within 2 hrs of the shot, cat vomited again. While on the antibiotic, she went two days without vomiting but started back up.

    I have an appointment on Friday to get the blood panel work done since she is still vomiting. In between all of this, my other cat vomited once and then tonight they are BOTH vomiting. I Googled Iams and vomiting and came across all these reviews tonight. I ran to the store and have bought a bag of Rachael Ray Nutrish and have thrown out the Iams. Will be showing the reviews to my vet on Friday. Along with this, my 10 yr old cat’s fur over time has gotten rough, shedding like crazy, and has patches of skin that look like bad dandruff, plus just lays around A LOT, which matches what all of these other posts are saying. What is our recourse?

    We originally started getting our kittens Blue healthy kitten food and they loved it, but as they hit a year old we decided to try Science diet urinary tract dry food because we were told cats are susceptible to UTI'S and our local store didn't carry anything like that in Blue brand. We did notice occasional vomiting so thought it was the brand and switched to Iams. Almost immediately they were both vomiting undigested food. Projectile vomiting at times and then the one sickly kitty became lethargic, sleeping more than usual, crabbier than usual and then heavy salivating so today we decided to just switch them back to Blue and I recently added a probiotics immune booster to their canned food. I decided to see if their were any complaints on this food and found this site with reviews with similar problems and wise! I'm so glad that we decided to switch before it was too late.

    We have 12 cats so I decided to give them some variety in the dry food we give them. A few years ago I began buying Iams dry food in various types to have alongside the Purina blue food I give them. For a long time the cats ate either type in the same quantity. About 6 months ago I noticed they were not eating the Iams, and would not eat until I put the Purina out for them. Not even the feral cats on the porch would eat it. I came looking for a way to ask Iams if they had changed their recipe, and found these warnings. I threw away the 3 bags of Iams I had just bought and am looking for a new "other food" to give them.

    I bought the food at Chewy.com but I am not putting a receipt in here. You will have to trust that I actually bought this food. In April, I decided to see if I could give my (older) cats something different and tasty to eat. So I bought Iams Cat Food. Iams Urinary tract formula. What I am reading in these reviews match my experience VERY closely. I have male/female siblings, the male was pretty unhealthy, so I thought it a coincidence that he became lethargic and sort of ill. He then died of a (not diagnosed) problem that from what I have read matched symptoms of congestive heart failure or feline asthma.

    I continued to feed the female the food mixed 1:1 with a lower calorie urinary tract formula food they ate for years. After a few months she is showing the same symptoms as the male did. Lethargy, hair lose, dry/unhealthy hair, coughing fits, and additionally constant (unusual) thirst. This has scared me enough to throw out the remainder of the food and start again feeding the (Purina) urinary tract formula. If you are feeding this food and see these symptoms, STOP! The death I saw of the first cat was horrible and traumatic... gasping for breath and obviously terrified! I would avoid feeding this food and find something else. I very much wish I had read the reviews before I bought the stuff!

I’m not even sure why but I decided to read some reviews and became terrified from everything I read. About an hour after she ate, she was just acting very strange almost like she was confused, I could tell she wasn’t herself and became sick and puked most of it up. I tossed the bag out.

    The only reason I gave them 1 star is because they wouldn't allow keeping them all blank. I started feeding our 3 cats Iams Urinary Tract dry food in January to give them something different. By March, 1 cat, who had been healthy died unexpectedly of Kidney failure. He started losing weight right after I started them on it, but, I just thought it was because I was restricting his food intake to get him to lose weight. But, he lost 5lbs from February, when he was last at the vet to March when he died. Now, my 2 other cats are starting to throw up on a daily basis after eating their dried food (they don't get sick when I feed them their Friskies canned food at night), and their stools are now black.

    After reading these reviews, I am convinced this food killed my 1 cat & is now hurting my 2 others. I will be throwing out what we have left of the Iams today, after reading these other reviews and heading to Target to get the Purina I was buying before. Someone needs to look in to the problems with this food before anyone else loses their furry loved one.

    Bought Iams food when pet store was out of our usual Purina product. Within one week I realized my cat was drinking much more water - as much as 24 oz. in a day - and producing copious amounts of urine. His normally silky coat had become coarse and dry. There was some weight loss and an obvious decrease in energy. I thought to check online and discovered many complaints about this brand causing serious health problems in cats. We immediately resumed using the Purina brand. In 4 days my cat was drinking reasonable amounts of water and urine output had returned to normal. He looks better and seems much more his old self. I hate to think what might have happened had my cat continued to consume the Iams food.

    On a whim I decided to buy a bag of Iams Weight & Hairball Control (light blue bag). This is the first time my cats have ever tried any Iams food. After 2 days of feeding my 3 cats this food they became sick with one cats almost dying. They all three became very lethargic “out of it” acting the first day. The second day of feeding the cats Iams food 2 of them were still lethargic, not eating or drinking and our oldest cat was in bad shape. He could barely walk, his face was swollen and he kept his mouth open and shaking. He looked very bad and we thought he was dying.

    We took the oldest cat to the vet and they could not find anything wrong with except for he was a little dehydrated. The vet figure he had got ahold of a bug or a frog and sent him home with us. We had not yet suspected the food. The next morning all 3 cats were still not well and our oldest was in very bad shape. I started to suspect the food and removed it from their bowl and gave them their regular food. We then took our oldest one back to the vet where they still could not figure out what was going on. The vet gave him a steroid shot and some antibiotics and sent him home again.

    Since stopping the Iams food and switching back to our original food, 2 of the cats are back to normal. The oldest cat is getting better but is still not back to his normal self. The only change that could have sickened my cats was me giving them Iams food. They got sick after eating it and got better when I stopped giving it to them. It only took 3 days of feeding them Iams to almost kill them. I will never ever feed my animals another Iams product again. Food that acts like poison should be pulled from the shelves. Waiting on blood work results to confirm what made them cats sick. If it’s the food (which I’m 99% sure it was) Iams will be paying my vet bills.

    I picked up a bag of Iams Healthy Cat dry food. I thought, “It is Iams; it has to be good.” One tortoiseshell cat died mysteriously. Fine one day; dead the next. Gable, my oldest cat who was reasonably healthy, started sleeping an awful lot and losing weight. I thought it was her old age. She died Sunday. I had a rescue kitten who, again, was healthy and active. It died an hour after Gable died.

    This morning I heard one of the other cats give a loud cry; I found it dead. Nothing has changed here as far as cleaning products, cat litter, only the food. I started looking for whatever happened when I found this website. I also noticed on the Iams package something about being imported from Malaysia. Was this food responsible for the death of these otherwise healthy cats? Another thing I noticed was the amount of water that was being consumed. Usually I fill up the bowls first thing every morning. Recently, it has been three or four times a day. So much of what I read on here sounds like my fur babies. I am beside myself that I could have caused this simply by buying a different brand of food.

The vet and myself decided to monitor his weight for a couple of weeks and see if he loses anymore before we go ahead with a scan.

    We started our three cats on Iams adult cat food about a month-and-a-half ago. The cats seemed to like it at first, but then each of them started throwing up little bits of cat food after they ate it. Two of my cats have become very lethargic and lay around almost 24/7 now. Their coats have gone from beautiful and shiny, to dull and Messy looking. I came online to look at Iams recipes and found so many reviews about this cat food that resemble my review. We are changing our food today. I will never go back to Iams. Our cats have the same symptoms these other cats have and we had lost two kittens previously for unexplained reasons, also eating Iams food. I am sickened at what this company has become.

    I used to work in retail and sell this product in the 80s. It was one of the very highest rated products and it had earned that rating. Now it has earned 0 Stars although that was not an option. So I gave it one. We are switching to Blue Buffalo Wilderness which is lots of protein and no grain. We bought several bags of cracked corn to feed my pheasants with in the winter where we live and many of them came with mold in them. Moldy corn. I believe this is what is going into the cat food. Just my guess! Get your cats off of Iams if you want them to live and be healthy.

    My beautiful cat Sammy was fed Iams hairball formula dry cat food from a year old. A few months ago the food was not its usual color or size so I just figured that they changed the look of the food and fed it to Sammy. Two weeks into the food he had lost a substantial amount of weight. He would vomit the food randomly. I thought at that point the food was accidentally packaged in the wrong bag and that maybe it was a weight loss formula. I stopped feeding it and went to the store to get another bag and it was the old looking food. I said, "Ok, it must have been packaged wrong." Sammy put all his weight back on and was looking great again. His bag emptied and I went to get another bag but to my dismay it was the smaller different colored food again.

    Now I knew they did change the formula. I had no choice but to feed him the food until I could get back to the store to get him something else. It was about 2-3 days. Sammy did not even want to finish his food and started looking like crap that quickly! He was still happy and acted normal but just very unhappy with the food. I purchased Purina shredded select for him after some research on cat food and it was rated great. Also when researching I found these horrible reviews and felt so guilty not having researched this sooner. People's cats actually died! I mixed the Purina with the Iams to transition him to the new food.

    Sammy went bonkers for the new food. He looked great again within 3-4 days. We were so happy! Apparently I did not transition him soon enough. The Iams had already done its damage! My beautiful healthy Sammy had a heart attack and died. One minute he was happy and meowing and I looked away and then looked back at him and he was dead!!! I am still in shock and feel so guilty for not researching well enough the minute I saw that food look different. Whatever those people did to change that food is injuring the cat's organs and FAST! Sammy knew and tried to tell me by not eating well. I got the hint too late. Don't make the same mistake before you lose a best friend too. Please DO NOT USE IAMS if you love your animal.

    I have been using all types of Iams cat food for the past year. We switched from another brand. I noticed they don't need to eat as much as they use to. We were going through 60 pounds every two weeks. Now we go through 109 pounds every 5-6 weeks. We foster as well as taking care of our own. I did notice that if I didn't mix the two types of food properly to wean them off the other brand it would make them sick.

    We have a blind cat who has kidney failure but it's NOT due to the food. He was born with it. It was said we would only have him 1-3 years. He is three years old and his kidney function is still the same. We also have some cats as they got out of their kitten stage did get leaner and some have always been thin. Then we have some cats that probably are way overweight. I'm not disputing the experiences that people have had on here. I'm just saying my cats have improved In most aspects.

    I thought, hey I love my cats, I should take the best care of them I can. So I splurged and bought a $40 bag of IAMS. I was well prepared for the transitional phase from one brand to another. I mixed the 2 foods for a week or 10 days gradually making the mix more Iams. It has been a month!!! Both cats still have extreme diarrhea. I am going to get them new food tomorrow. They have had diarrhea on my bed, it soaked through my quality mattress cover, onto my expensive mattress. They have had it on my pillow, on my carpet, on the hardwood floor, on my laundry, on my bathmat, in the tub, ON MY END TABLE AND MY KITCHEN COUNTER!!!

    I will be contacting IAMS in the morning as well as getting new food. I will be demanding a full refund, a cleaning service, replacement of my mattress if it cannot be cleaned spotless. Of course they will not do those things so I will take every opportunity to bash them and share my experience on social media!!! DO NOT BUY THIS!!! I am looking into making a homemade cat food, since they don't eat too much I think I will be able to put good use to my healthy leftovers!!!

    I saw this food in one of my local pet shops and decided to give it a try. It looked quite reasonable at first. After about a week, my cat started acting a lot differently and becoming unresponsive to my usual calls. She was constantly out of energy and sleeping more often than usual. Her fur was starting to get extremely rough and patchy... I immediately knew that it was this food that was doing this. I luckily caught this early, if I left it for another week, I would of taken her to the vet. Her condition was shocking, she seems like she was extremely sick. She is doing much better now since I have given her old food back. Her fur is silky again and she is much more playful and happy now. This food should be banned completely from every shop in the world and the business that made this food needs to get a massive fine. They are poisoning innocent cats!

    Just over two years ago I had to adopt my mothers two cats because she is suffering from dementia, one of those cats she has had since it was born and we think Spencer was 11 years old. Notice I said was... I have a picture I took of him on 11/26 and you would go, "Fat beautiful cat." Just a few days ago he seemed fine, we were gone for not quite 3 days. Left the cats food and water as we always do since they are 100% indoor cats. We notice Sunday when we get home that in just those 3 days he looks terrible, weight loss and very lethargic so yesterday we take him to the vet.

    One question they ask is what do you feed them? I could see the bag but could not think of the name so started searching and found this site. Iams Hairball in the orange bag is what we just started feeding the cats in last 4-6 months, we were on either 2nd or 3rd 7 lb bag. Is this why we just had to put our cat down, why I spent $1,300.00 in the last 12 hours because I know it's what my mother would have done? I'm not very happy now that I've seen this and I hope Iams is reading this. I will also be sending this email directly to them and plan to demand my $1,300.00. I know what their response will be so I will be monitoring this very closely for class action status. VERY UNHAPPY IAMS BUYER.

    I've never bought Iams brand before because I've noticed that seem to show up on a lot of recall lists. About a month ago, I reluctantly bought Iams Senior Cat food because it was the only senior cat food in Target. Both of my senior cats seemed to be doing fine with it at first. One of my cats had a bout of diarrhea, and threw up a couple times, but I put that down to introducing new food. I noticed that my oldest cat stopped using the litter box shortly thereafter. Both of my cats started having very dark, almost black feces, and one cat appeared to have crystals or mold in hers. The stool wasn't tarry, so I chalked that up to there being too much dye in the food. Both of my cats also had worms - one with tapeworms, the other roundworms, so I thought any sort of oddness might be because of that. I gave them both the same combination dewormer, and that cleared up the worms, however the poop weirdness otherwise continued.

    About a week after deworming, my eldest cat had lost a significant amount of weight, which was alarming because she is a petite cat who doesn't weigh much - 6.5 pounds at her healthiest. She is now down to 5.4 pounds and is very weak and lethargic. She still eats her food, but doesn't seem to take more than a few bites. Odder is that she gobbles up her treats, so she doesn't seem to have an appetite problem. She still doesn't use the litterbox which, with her, is only typical when she's sick. I waited a couple of weeks to see if she would gain weight after the worm was gone, weighing her every day for a week, and her weight has stayed the same. At first I thought she must have had a bad reaction to the medicine, but I've searched the Internet and have been unable to find any similar case involving the medicine. The medicine was also suitable for kittens, so I don't believe it was bad for a cat in her weight range.

    After reading these other reviews, I believe it has been the cat food. My other cat seems fine, but is obese, so I'm not sure I'd notice weight loss in her immediately. I've begun giving my skinny cat Meow Mix wet food, and I've already noticed a significant increase in her energy level. She is now walking around, cleaning herself again, and seems slightly more steady standing up. I'm now beginning to suspect that this food contains a toxin that was being absorbed by the tapeworm, and that killing it actually put her at risk, as crazy as that might seem. I am going to give it a week before being definitive, but as for right now, I am warning anyone to read this to stay away.

    We adopted two beautiful, vibrant, healthy kittens on December 23. We started them on Iams Kitten food because the food they had had at the rescue facility was not available in our area. After only three days of eating the Iams, they were experiencing life-threatening symptoms. By December 27 they had diarrhea and were vomiting, and had stopped eating and playing. On December 28 we took them to the vet. He could not find anything wrong with them illness-wise, but gave them an anti-nausea medication to see if that would help. They showed some interest in sniffing some wet food, but still would not eat and continued to have the digestive issues.

    They would not go near the Iams. Since they had been so healthy at the rescue and then became sick so quickly, we decided to look for the food they had been given previously and drove to the nearest place that carried it (100 miles away). They still refused to eat and were losing an alarming amount of weight. We took them back to the vet, who again found no definitive signs of illness. This time they received both anti-nausea meds and an appetite stimulant. By the time we got them home, they were ravenous and devoured the new (old) food. They have been eating almost nonstop since and are once again playing actively like they were before they ate the Iams. We will never again buy an Iams product.

    I have been feeding my cat Iams Hairball and Weight Control (teal bag) for years. I just noticed from reviews on here that she may be experiencing the nausea and lethargic symptoms from a recently released formula. I've only been feeding her the recent bag for a few days and all the symptoms came on strong. Came home to throw up piles all over the house. Took the cat to the Emergency and they said all her labs showed nothing wrong. A co-worker suggested it could be the food and now I'm not ruling it out. If you notice sudden changes in behavior and you've been using the food I'd say switch before the nausea kicks in. It's painful to watch and not really be able to help.

    I'm so glad I came across this website. I have been very frustrated as our 8 year old cat has been getting sick about once a week or so, often on one of my daughters' beds. The other day he puked on my daughter's arm as he didn't have warning enough to move, and had diarrhea under her bed. He was always healthy and ate the orange bag food for years. I de-wormed him thinking it might be parasites. That didn't work. Finally I decided to try changing his food before taking him in for a battery of costly vet tests. I picked up some canned grain-free food today and he scarfed it down. He's estimate he's lost about 3 lbs since around Sept when this all began. He's so malnourished now that he aggressively tried to eat some canned beets we had for dinner the other day. What the heck did Iams do to the formula? I didn't even know they changed it but Joe I demand to know what the changed ingredients are to make so many cats so sick!

    Did you know Mars (the parent company) uses GMOs in their products (including candy). God knows what other shortcuts they've been taking. I'm

    very disappointed there has not been a recall. Clearly the changes formula is TOXIC!! I'm just glad we found out before they developed something chronic like organ failure or diabetes. Iams should be ashamed. I will boycott all Mars products and we should all spread the word. Customers have a right to know when formulas are changed, especially when clearly toxic ingredients have been added. Our pets deserve better!

    I purchased the IAMS weight and hairball care for the first time a few weeks ago because Target didn't have the grain free food I usually get. A couple of weeks in, I noticed that my cat looked like she had lost some weight and I thought, "wow, that seems fast". But then one morning, both my dog and cat threw up. My dog always finishes up her food if I don't pick it up. That's when I started to think this may be the cat food. This morning, she threw up again. Now, I am only feeding her a different brand of wet food because I'm afraid to keep giving her this. If she doesn't feel better after getting just her wet food, I'll have to take her to the vet. My poor kitty! I should have known. I remember hearing bad things about IAMS in the past, and I felt a little weird pulling it off the shelf. I should have listened to my intuition.

    I have a 1.5 year old male indoor cat who's never had any health issues. He weighed 15.8lbs & only ever had dry Costco brand indoor cat food. I decided to put him on this Iams Proactive Health Indoor Weight & Hairball Control (Teal bag) for weight loss & gave him smaller portions over the last month. He dropped 3.5lbs within that timeframe and I thought it was a good thing. That was until I started to notice he was acting different, stopped playing, eating, drinking, pooping, sleeping 24/7, groggy, drooling, throwing up with blood, very bad breath & zombie like. I took him to a vet specialist & had the two cat leukemia/HIV tests (negative thank god), however he was so anemic his gums were white & blood tests showed his red blood count was 12 (should be 28-42).

    Every time he ate this new Iams food he acted like he was starving, but he jolted away like he was in pain after just 1-2 kibbles. He'd attempt to eat again and had a terrified look on his face staring at the food. The vet found sores/pockets in the back of his gums where our wisdom teeth would be on both sides. The vet ran a tick blood test & we're awaiting the results tomorrow, depending on the outcome the next step are ultrasounds and X-rays. I've already spent $700 on blood tests, pain meds & an antibiotic. I've switched his food immediately to wet food & chicken broth so he could slurp it & he's thankfully been eating again (Blue Wilderness Salmon - has high protein & fat).

    I'd stop using this immediately, this is the only thing that's changed in my cat's life and it happened to be the same time these symptoms showed up. These reviews back up my suspicions & a local PetCo worker told me she had a customer come in this week with a similar story to mine who also used this Iams cat food. I'm contacting Iams immediately, this is ridiculous that it hasn't been recalled with all these bad encounters noted on this thread. Hopeful the new diet will fix these awful impacts to my poor baby.

    Bella used to eat all of her IAMS, not leaving any for later. I noticed the kibble was smaller and she was not eating all of her food when it was time to feed her again. I became concerned when she seemed to constantly be itching with allergies it seemed, and did not anything to do with her food at all. So I took her to the vet and got a shot for her. She seemed to be more and more like herself little by little. The change I noticed was with the new packaging, the plastic bag.

    That was about a month and a half ago. She is eating less again. After reading all these reviews, I do believe they changed their formula. She is not itching like that again yet, but she does not want to eat that stuff at all. Food was purchased at Walmart, and upon initial discovery I also got a bag at Family Farm and Home dumped it on top of the other two. We are now down to the two bags from Walmart mixed together. It seems that I am one of the lucky ones, my heart goes out to all who had to watch their babies get sick. Very disappointed IAMS! I will be stopping on the way home to buy something else, at KROGER.

Opie isn’t a picky eater, so getting her to eat it wasn’t the problem. The problem came when she started throwing up. She was vomiting twice a day, where before she maybe vomited twice a month. My boyfriend and I realized tonight that we started her on this new food around the time that the problem started. Reading the reviews of it just confirmed my suspicions more.

    Our cats have only ever eaten Iams Hairball Control... blue bag. Approximately 2 months ago, after purchasing the last bag, we noticed our cats wouldn't eat it. They would dump it or bury it but wouldn't eat it. After a day, they were hungry enough and finally ate it but they both started vomiting shortly thereafter. This is unlike my cats, and they have always loved this brand. My husband gave what was left to our neighbor's dog. The dog began to vomit as well! So I knew it was the food!

    I called Iams and they said the formula was recently changed... but the bag is exactly the same... so I wouldn't have known. She said they hadn't received ANY complaints and that the change in formula should've been introduced slowly. Well, had they changed the bag, I might have known it was a different formula but it's the same package without any mention of a new formula. The representative assured me there were no complaints about the food and she sent me a coupon for a free 7 lb bag. Now, I'm very angry seeing all of these complaints about their food because she lied!!! Never buying Iams again!

    I have 2 cats, 4 years old. They’ve been on the food for sterilised/overweight cats for their whole lives until now. When I went to buy more I was told that there’s a new improved range. I looked for an equivalent one to the food I’d been using but there was nothing, so I bought the orange bag: adult 1 plus years, with fresh chicken. “Supporting 7 signs of healthy vitality” apparently. Because there was no equivalent to the food I’d been using, this was in effect, a completely new food to them so I couldn’t introduce it slowly as you’re meant to with any new food. I wasn’t given that option. Neither of my cats would eat it and when they did, because it was all I had, they were sick.

    How ridiculous to bring in a completely new food without any warning and not to have any equivalent options for people who’ve been using the same one for years! Why ‘improve’ something only to make it worse?! There’s a saying: if it ain’t broke, don’t fix it.

An oral Barium contrast was then done to confirm there were no blockages. This contrast X-ray did confirm she had no blockages.

    Mushy Cat was given an anti-nausea injection at the clinic and sent home with oral anti-nausea tablets with really no explanation as to what was going on to cause the vomiting. It was later that evening that I started to put 2 and 2 together. I threw away all of this remaining food immediately. She seems to be coming around at this point.

    We have been feeding our cats Purina One Indoor Turkey & Rice formula for many, many years (probably about 16 years) and have never had any problems or issues with it. However, about a month ago when our cat and dog food delivery from Chewy.com was delayed and we were about to run out of dry cat food, my husband picked up a large 22 lb bag of Iams original adult formula at Target on his way home from work because they didn't have any of the Purina One in stock, so I told him to just get the Iams thinking that it would be fine.

    My parents fed both our cats and dogs Iams when I was a kid in the 80s and 90s with no problems, so I figured that would be a good alternative until our normal Purina One arrived. WRONG! Over the course of 4-6 weeks that our cats were eating this food (we were trying to use up the giant bag), we noticed that our cats' coats were becoming very dull and not nearly as shiny or soft as they usually are. Also, 2 of our 5 cats began throwing up multiple times a day and began losing weight. This has NEVER happened before.

    We finally stopped feeding the Iams and put them back on their normal Purina One and their soft, shiny coats started to come back and the 2 cats that had been vomiting stopped and were completely fine after stopping the Iams. After reading all of the other complaints that are almost identical to our experience, I feel very confident in saying that Iams is TERRIBLE, TERRIBLE food and should be avoided at all costs! Obviously, it's not the same food that it was when I was growing up in the 80s and 90s and has gone way downhill in quality. If you are considering feeding your cats or dogs Iams, DON'T DO IT!!!

    My 12-year-old, indoor-exclusive, short-haired, gray tabby cat has been eating IAMS brand dry cat food all her life. When she grew to adulthood, I switched to the Proactive Health for weight and hairball control (as the title suggests Iams PROACTIVE HEALTH Indoor Weight & Hairball Care Dry Cat Food). Since adulthood, she's gotten a measured 1/4 cup of food in the morning and once again in the early evening when I came home from work. For the past 8 out of 10 years, my Lovely has been eating this brand without issues. However, like so many other cat owners who rate this brand as poor... I'm too am doing so not only because of to the vomiting but because of other issued I've listed below.

    My cat has never been sickly nor does she have a sensitive stomach, however, for the past 2 years, she'd vomit each time she ate. Don't get me wrong, she loves the flavor and she'd gobbled it down like she hasn't eaten in a week. Without fail, 15-20 minutes later I'd hear her retching and then I'd come across the vomit pile(s). Soon after the purge, she'd trot over to her bowl...and the endless cycle began. I thought maybe she was just eating too fast so I'd intervene; divert her attention by petting her and telling her to take her time. Never wanting to miss a petting opportunity, she'd enjoy the love and slow down the shovel. Most of the time this worked but not always.

    Now that she was keeping down the food, for the most part, I began to notice her substantial weight gain. Surely vomiting the food isn't the method by which her weight was to be controlled...surely not!!! But this substantial weight gain wasn't the only change I began to notice: 1-Her coat, although soft, was now greasy - not shiny. It separated into clumped bands of hair across her body from her head to the tip of her tail. 2-Her coat was covered with dander - a problem she'd never had before. It got so bad she looked like she had a severe case of dandruff. 3-Excessive shedding. Now I know what you’re thinking, animals shed, but this was insane. She's a short-haired tabby...she only sheds during seasonal changes. I couldn't touch her without having handfuls of fur over me, the couch, the floor or the fly-away clumps of hair floating in the air flow generated by the ceiling fans.

    No amount of brushing would stop the shedding, get rid of the dander, or make her fur look sleek and shiny. Eventually even distracting her during eating didn’t stop the vomiting entirely. There was an endless cycle of eating then purging, weight loss and then weight gain. That's dangerous for a human, I can only imagine what it's silently doing to my pet. I finally stopped feeding her the IAMS brand altogether. After some trial and error with other brands, I finally found a brand she loves. Every issue I mentioned above has corrected itself. And even though she's 12 years old and an only child, she now runs around like a kitten.

    Many reviewers mentioned they noticed the vomiting after the switch from the pink bag to the blue and I concur. The other issues listed above developed over the last year-and-a-half. I think it's safe to say that whatever formulation changes made, substantially decreased the nutritional value. I won't be buying any IAMS brand again nor can I recommend it any cat owner. It’s really sad to see a once GREAT product turn a blind eye on quality and customer satisfaction.

    About three weeks ago, I bought some Iams cat food for weight control/hairball. My cat has never been a picky eater; he is 15 years of age. From the start, he began to lose his appetite; he would not clean up his food. I attributed that to the change of food; my grocery store does not carry his regular food, so thought the Iams mixed with his regular diet would be a good choice. WRONG. After two to three weeks, he was really dropping weight. He began to leave more and more of the Iams. He became lethargic and almost anti-social. He spent more and more of his time in his favorite hiding place. He had large, loose, soft stools. I became very concerned and decided to take him to a vet and change his food.

    This was late Friday evening; vets are not available on weekends except for emergencies. I did not deem he was in an emergency situation. I started him on the new cat food; he ate an entire feedings. Later that evening he was asking for more; he had perked up and was starting to demand my attention. It is Monday morning; he is back to normal, hungry, social and is no longer lethargic. There is, apparently, something toxic in the Iams cat food.

    Two weeks ago, I bought Iams hairball control food at Target because the store did not have our normal Purina hairball food. I gradually switched my cat over, adding a small bit of the new food to the food she was used to and gradually increasing by tiny increments each day to avoid an upset stomach. In the last few days, she has vomited over 8 times, and yesterday I found blood in both her vomit and stool.

    She has not acted sick, and has continued to be very affectionate and playful, but obviously I took her to the vet today because these symptoms are terrifying. The vet could find nothing physically wrong with her and took blood to test to be sure, but after reading these reviews, I have thrown the Iams food away and switched her back to Purina. No vomiting or bloody stool tonight, but my cat has been extremely flatulent and it's still really alarming. I will amend this review if the blood tests reveal a different issue, but the food certainly seems to be a likely cause.

    Back in November of 2011 Iams had a recall of their pet food. Sadly my cat passed away from this poisoned food. Iams assured me that they would pay for all my vet bills and that they would pay for funeral costs (they would not pay for me to replace my cat and put no value to my cat other than the direct monetary value of the loss). I agreed to this payment, signed all the documentation that they asked us to sign and waited for payment. My assumption was that because they were involved in a legal case that my payment was going to be slow to come. Boy was I mistaken. They have never sent payment. I called them numerous times and they just told me that they would not send payment and the case was closed. So they basically lied to me. How can a company be so callous to a customer? Cost me thousands of dollars and did nothing to cover the costs.

    I have 4 cats, ages range from 8-1/2 to 6-1/2 years old. For the past 5 years I have fed them Iams Proactive Health Indoor Weight and Hairball Care with no problems. Some reviewers said that they noticed issues when Iams packaging changed from the paper type to more plastic – I did not. My last purchase was a 7 lb bag, which I normally get. All kitties are fed twice a day, ¼ cup each feeding. We were about halfway through that bag when Sassy (my smallest & oldest) would only eat a couple nuggets then walk away. I thought maybe she had an upset tummy, so after 3 feedings of her not eating anything, I gave them all some Royal Canin dental (which they get as treats). Sassy ate those just fine!

    The following day, Dylan only ate half of her dish and threw that up. I decided to stop after work that evening and pick up some Cat Chow (not bottom of the barrel food, but not premium price food either). Both Sassy & Dylan had no problems eating every nugget in their dish… Bottom line – I don’t trust feeding the Iams to them anymore, especially after reading the other reviews, what I have left will go in the trash and will look for an alternative dry food. My kitties are my children, and as every good pet parent knows, you do what you have to do to protect them. I am thankful I didn’t wait too long before coming to this conclusion and hope I made the switch in time…

    So my cat Rockie, my love and life has been a puker because he has a sensitive stomach. So, I decided to switch to Iams. Heard it was good for cats and so forth. Well, for the past couple of days I noticed my cat losing weight. My fatman turned to bones. He wouldn't eat, he barely drank. Now mind you he didn't puke on this food, just colored food.

When I called the vet to check up on him cause they had to keep him because he was dehydrated and they wanted to observe him, vet advised that he was eating a little and drinking a little cause they couldn't insert an IV.

    I have 2 Ragdoll cats, sisters that are 10 years old and have grown up eating Iams Dry Food mainly the Proactive Health Indoor Weight and Hairball Care. That's what their breeder recommended and I had feed my previous cat. Wednesday both cats refused to eat. They walked away when I set the food down which is very unlike them. This continued for days along with diarrhea, the smaller cat having a terrible case with a little blood showing in her stool as well. By Saturday both cats were acting lethargic and still not eating. I ended up taking them to the emergency vet which found them both dehydrated. The vet couldn't find anything wrong and asked if I had changed anything, nothing had changed. They were given anti-acids and anti-nausea medicine along with a bland diet like chicken breast or chicken flavored baby food.

    Two days later they're doing great and I decided to go online to see if there were any issues with Iams. I couldn't believe all the reviews that sounded exactly like what we had experienced. I had bought a 16LB bag of Iams Proactive Health and just opened it right before the cats started showing signs of being ill. I noticed for the first time too that the bag was plastic instead of the usual paper. Whether or not that has anything to do with it, I don't know but something has changed and is very wrong. I've thrown out the bag and plan to call my vet in the morning to ask what dry food he recommends. I believe Mars took over Iams several years ago and evidently isn't living up to the previous standards. Let's hope for everyone's sake that they figure out what the problem is before many more beloved pets become ill.

By Wednesday when he was showing no improvement, we took him to the vet and after a battery of tests and an overnight stay, the vet declared him healthy. BTW, he did not vomit while at the veterinarian's and it is important to note that they fed him a food other than Iams. The next day he came home, ate some Iams and promptly vomited again. I bought a different brand and he stopped vomiting and by the end of the weekend, looked healthy and happy again.

    I have recently started buying Iams protein formula or senior care formula for my 12+ year old cat. Before I was lax in what I fed him. Whatever I could get for a good price because he's not picky and I am on a limited income. As he is getting older, the quality of foods (fillers and additives) are getting harder for him to digest.

    Last month I was buying his food and they were out of the senior and protein (my go to when I can't get senior). They were even out of the adult (green bag) in the size I needed. So I decided on the oral care. That was last month. Almost 2 months ago. Since giving him their oral care formula, my cat had slowly stopped eating. But was always crying for more food. One day I noticed he didn't seem to weigh as much, and I noticed light bleeding in drool (I didn't think too much about the drool because cats with long fang teeth are prone to a little drooling).

    Immediately the next morning as it was too late that night, I called the vet. This was almost a week ago. Apparently he hurt a tooth and developed an infection at some point since eating the oral care food. He weighs 12.5 pounds, a considerable difference for an almost 20 pound cat. He cannot eat hard food and is having difficulty eating moist food. And is now at the point that he doesn't want his food liquified. He is on antibiotics for the infection and I am now trying to come up with the $400 or so that I will need to make a dental appointment.

    My cat has been very healthy for as long as I've had him. Has had minimal problems, only needed the vet 1 other time before this. He was a very strong and active cat. And now he is reduced to the state he is in. And unable to eat. As far as health, the vet was surprised that he was in such good health at his age and surprised that his teeth were as good as they are. I have had no problems with any of the other Iams formulas that I have tried. And have also given my dog Iams. But I would suggest to think twice before buying the oral care formula.

Yet surprisingly they stock all of their dry foods and wet dog food in all other stores but the wet cat food can only be purchased at those 2 locations and have been out of stock in our city for a month.

    If that is bad enough many would have to take 1-2 buses to get to those locations. Clearly the company could care less that elderly those with no cars etc. must go out of their way if they truly wanted their product.

The last time I purchased a large bag it was in a plastic coated bag, rather than paper. Maybe this is the culprit... or the formula has changed. Since Iams does not publish the food contents, simply stating it's a proprietary formula, it's not possible to figure out what, if any, food content changes have been made.

    After years of using IAMS indoor cat food, our cat now has chronic diarrhea. This happened with the very first bag of food after they changed the packaging to the new plastic bags. He has been to the vet, has had antibiotics, and it has been 3 weeks of chronic diarrhea for him. It only took 2 days for the diarrhea to start after he ate the product in the new plastic bags. He initially had blood and mucus in his stool but the antibiotics from the vet stopped that within two days.

    After reading the posts on this and other forums, we suggest that anyone with this issue call the FDA and report it. Calling the company itself may not be enough, the FDA needs to investigate.

They tested his stool and did bloodwork/xrays and couldn't find anything causing the issue. They sent him home with antibiotics and something else for an upset stomach/GI meds. It seemed to help for about a week. Then the bloody stool started again only this time it was all over my new carpet and not the litter box. We went back to the vet, he was given more meds and sent home. This time they didn't work. I talked to one of the secretaries who said it could be a sensitive stomach and to try Purina pro plan sensitive stomach. I switched.

    A day or 2 later we noticed he was using the litter box and the blood was gone. My other cat, also started eating the new food as well and actually gained a ton of weight. I didn't realize my older cat wasn't eating much of the Iams previously because we would also give her a half can of wet food twice a day due to her dental issues. About a week after we switched food we noticed our new kitten being lethargic and not playing nearly as much. We called the vet who didn't have an open appointment until 3 weeks out (August 1st) and because he was "JUST lethargic" and still eating and drinking, and pooping ok, the secretary didn't feel it was an emergency and needed to be seen right away.

    When we finally took him, he was severely anemic. Blood counts were 11. They checked him into the hospital, gave him steroids and antibiotics. His RBC came up to 27 and he was sent home. At home quickly seemed to get worse. Took him back the next day his RBC dropped to 15. He was then hospitalized for 5 days straight. His numbers kept going up and down. Highest RBC was 19. Vet said feline leukemia and HIV test were neg. They talked about possible FIP, but ruled it out because there were no other symptoms but anemia. We went to visit him on the 5th day while he was at the hospital and vet said they done everything and to consider his quality of life.

    At that point we consulted with 2 additional vets in the animal hospital who all agreed they don't know why his bone marrow wasn't working and said it may be a genetic bone marrow issue and suggested we let him go. I obtained his records and my cat and went to a 4th vet with 42 years experience. He read the records and asked several questions and was baffled as well. Suspected poisoning, but said the meds in the hospital should have worked. He tried Chinese herbs and acupuncture and was able to get his RBC at consistent 16. My kitten then started seizing which lasted a couple days then stopped. A few days later, he couldn't walk at all for 3 days and was defecating all over himself and his bed. It was time to let him go. We all were so heartbroken. Meanwhile my other cat started to eat more (new food) and actually seemed a lot more active. My 5 yr old actually said our old cat and our kitten switched places.

    Yesterday my mom contacted me and said there was a stray kitten at the neighbors and asked if I wanted to look at it. We saw and fell in love with it. We got a large dog cage and got a nice setup away from our other animals until we could it in to get vaccinated 2 days later. I still had Iams kitten food left over from our old kitten and fed it to him. This new kitten was so tiny... maybe 6 to 8 weeks old. I crushed the food up and mixed it with bottled water to make it soft until I could get soft food the following morning. The day we got it, it was running around, playing, pooping ok, using litter box and purring up a storm. I woke up the next morning and checked on him. He was ok, happy to see me, but I did notice diarrhea all over the cage. I cleaned everything up and just figured it just had to get used to the new food and I would buy him something better on my lunch break.

    I carried the kitten around before work and as the kids went to school and put him back in his place before I left for work. My husband came home to it dead. The ONLY link between the deaths is the Iams Cat Food. My husband was skeptical until I found this page. We are convinced this food killed both of my kittens. I figure my older cat refused to eat it and that's why she was so skinny and always seemed so unhappy (I thought it was her teeth). Now I'm sure my old was only eating the wet food I gave her... 1 can a day as she knew the Iams was not good. I cannot believe this has happened TWICE!! I will never feed any of my animals Iams again. I strongly believe it may be the new packaging or ingredient. They need to take this crap off the market so another family doesn't go through the hell my family has been through the last several months!! Sorry this is so long, but I feel all these details were necessary to share.

    2 bags of cat food dry, in the new plastic bag, were bought from Shopko in Taylorsville, UT, have made my senior cat so ill that I have to put him down. He was a very healthy 18 yr old that was still very active until I started giving him the Iams in the plastic bags. I had switched him to Iams Senior in the paper bag and he really loved it. But once he started eating the food in the plastic bags he began eating less and less until about a week ago he stopped eating at all. He became weak and lethargic and now seems paralyzed he is so sick. He's so stressed his breathing is rapid and shallow and he can't move. His eyes are still bright, his gums look good but he's really scared. He's can't sleep because he is so stressed.

    My heart is broken and I'm angry with Iams and Shopko for producing and then selling such a toxic food item! Is there any recourse from these two companies? I feel I have to throw away about $75 in food since I have temporary custody of my daughters cat too. Thank goodness he doesn't want to eat the Iams!

    Always feed this to my 12 yo cats, as well as varying formulas of Iams dry food, and sometimes Science Hill and have never had a problem - UNTIL RECENTLY... My cats were not eating much, very odd for them, and after a week they appeared to be losing weight. I called the vet and was about to get blood work as I thought they were sick. But then I thought maybe it is the food. I purchased another small bag of the same Iams hairball/weight control formula and they gobbled it up immediately! SO... Something is wrong with that 40lb bag that I purchased from Walmart (in Central new Jersey). I searched online to see if there was a recall but found nothing, except I did find previous entries here on this site where the person's cats were getting sick from same brand/formula recently.

    I had purchased the food in February. I have been a true patron of Iams for over 20 years with my pets. Overall I think the food is good for my pets so I hope this was a fluke. I will call Iams to report as well. The food has been thrown out, which cost me over $30, I hope they compensate and take the claim seriously to protect others.

    We have been feeding our cat Iams Dry Cat Food for Indoor Weight and Hairball Control (turquoise bag) for the last couple of years without a problem until now. I bought a new bag at the beginning of April (2017) at Walmart and for the last couple of weeks he has been throwing up very frequently after eating it. I am concerned it could be the cat food. I called the customer service number on the bag to make a report. They said there have not been any similar reports made to them recently. However, I don't know that they would necessarily tell me even if there have been. I saw the other review written here (April 2017) stating a similar issue with their cats. It makes me wonder if it really is the cat food. If this is happening to your cats PLEASE report it to Iams. They are sending me a voucher to buy a fresh bag, but I am a somewhat reluctant to do so.

When the 7 lb bag ran out we got another at grocery store and after I fed to my cats some of they were throwing up. One of them threw up

    every time he was fed (morning noon and night). I checked bag ingredients and to my shock chicken is not longer the first ingredient!! Now it is byproducts! Needless to say I will no longer be buying this food - now I bought Royal Canin and no more throwing up! IAMS should have let it be known they changed ingredients - they are trying to increase their profits at the expense of the pets so switched to the cheaper BYPRODUCTS!

    I switched my cats over to Iams dry cat food, for weight management, about a month ago. I bought three bags. I went through the the first bag, mixed with the brand food they were initially on for a long time. Now I'm halfway through the second bag. I feed the ferals outside as well. I noticed one of my indoor cats, Max the male had diarrhea but I just thought it was due to the switching. I gave them other canned wet food as well, a little once a day. I switched over like suggested by the veterinarians. The male cat, Max would not stop with the diarrhea. It was literally all over the litter box, on rugs, and by doorways. I again just thought it was him because my female looked like she was doing fine, so I thought, because she was eating it. Then my Male started to vomit, and I had to bring him to vet. After lots testing, X-ray, and bloodwork, they can't really find anything.

    I use a natural deformed to see if this is the culprit, and as recommended I do the boiled chicken and rice, and gave him pills for nausea. He started doing better. I noticed he was back to his old self, at least no vomiting and the diarrhea had seemed to stop. Well a few days go by, and so I started adding back the Iams. The male, Max, gobbled it up, while the female Luna, who was not sick would not eat the Iams at all. The symptoms came back for Max, and now Luna is sick. There's no doubt in my mind it's the Iams! I am so mad that as a consumer, we spend a little extra to keep our babies healthy, and here we are unintentionally poisoning them. Something needs to be done. I will never, ever buy Iams again, and I am throwing out the last two bags I have. I am even concerned for the freaks outside as I cannot monitor them or their defecation process but they don't look well.

    Saved the life of my cats! I had fed my cats IAMS Low pH for years. It controlled urinary crystal problems and they enjoyed the food. When I moved to another state, my veterinarian did not provide IAM products, so switched to a Royal Cannin Low pH product. After 3 years when I opened a bag, the cats turned up their noses. I called the company to see if something had changed and they said no. So I continued to feed it to them.

    After a period of time one cat developed loose stools that contained mucous streaked with blood and were very smelly. She was put on a probiotic that cost me $1/day that helped some but did not solve the problem. A year later my other cat dropped from 8.2# to 5.8# in six weeks. After the expense labs, radiology nd of trip to a specialist, the cause of her inflamed liver, pancreas, etc. was not found. One antibiotic did not help.

    Because I had two sick cats, I decided to check online reviews on the product I was using. Lo and behold, I found many reviews of similar problems for cats and dogs--no problem for years, then either problems with bowels or rapid weight loss and even death. I got a prescription from my vet and I was able to get IAMS Low pH from another vet in another town (I now get the IAMS through Chewy.com). In a few weeks, the first cat had normal stools, and after 8 weeks my second cat had normal blood lab reports and had gained all of her weight back. IAMS saved the life of my cats.

    We have an 8-year-old "dog" like cat that will eat until it exploded if you left food out. We have a 5-year-old "cat" like cat that will nibble here and there (if we COULD let him) if we didn't have to babysit breakfast and dinner times. There was a time when both cats had gotten a bit overweight and the 8-year-old "big guy" got a lot overweight. I am not sure how the company pulled it off but I switched to this from regular Iams adult cat food. They both lost what weight they BOTH needed but neither was starved. They both received a measured amount and they both lost the right amount for their size.

    The big guy was a 20 lb cat but is now down to 16-17 lbs (depending on how much we watch and protect "Lil guy" from being pushed out of the way). Lil guy was at 15 lbs which was "ok" but should be around 12 or 13 lbs. In the same time big guy lost 6 lbs, Lil guy lost his 2 pounds all at a healthy pace and now both are more active and "kitten" like in behavior. I know they will live to be at least 18 just like the cat we had that passed away earlier this year. He was also on the same cat food but he was allowed outside. Our cats are not.
