Hills Cat Food Reviews

I noticed recently the consistency of the food changed dramatically and can even vary case to case. Then I noticed the "improved formula" on the label. All of which explains the reaction of my 11 year old cat who has been on the original for 9 years. What a relief at that time to finally find a food she could digest without chronic diarrhea and vomiting. This change in formula has put us back at the starting gate. I'm sure there are others feeling the same effects. I purchase my food from Chewy.com and will be sending them a similar complaint.

Our sweet Simba was diagnosed with urinary crystals 2 years ago. I had read a lot about cat diets and was not on board with the idea of a medicated food, but after his 2nd bout with the crystals we had to follow the vet's advice and give the Hill's prescription food a try. It did seem to help with the crystals, but after a year now, he suddenly slowed his eating of it. He was on the dry food. He had over the past months had more and more frequent episodes of vomiting. Sometimes hairballs, but other times not.

So I'm going to vent here. I tried to send an email but the webpage "isn't working". I am SO very tired by animal food companies messing with the food. NEW AND IMPROVED my foot! I USED to have three cats. Now I have two. My oldest was diagnosed with IBD 5 years ago. I never could get him on to any food that would stop his vomiting. I finally had to let him go last week. Now my other two cats. One was put on to Science Diet Z/D canned and dry because she's starting to have an issue with several foods (don't ask, but understand I literally have tried EVERY food out there... Don't believe me? Then ask and I'll send you the list.) On the Z/D she has now cleaned her entire belly from mid waist to between her legs of any and all fur. It is red with scabs. And she's terribly bloated.

Hill's Science Diet cat food causes obesity and diabetes. If you don't believe me, read the rest of the reviews! I've had issues with Hill's Science Diet Cat food in the past. I had another cat that I adored die from diabetes and he was fed Science Diet. I thought at the time that it was just something that happened. 12 years later I'm here again but with 3 cats. They eat it and either throw it up and don't seem to not be able to get enough. My cats are fed at certain times and get wet food as well. This is worse than the cheap cat food. I've switched to a better brand that hopefully can reverse what Hill's Cat Food has done to them. This is poison. Please spend more or even get cheap brands. Your pet will pay dearly if you don't. Poison. Complete poison. I'm so mad I can't see straight. You need fed this crap.

I have used Science Diet Original for over 15 years including when I ran a cat shelter. It was expensive yes but the health of the animals was worth it. It was the only thing I would buy my cats and it kept them healthy. I'm not sure what happened. You switched bags and decreased the amount in the bag and apparently changed the formula. I would have lived though unhappy with the new bag and decreased amount but the new formula is making my cats sick. My cats would only eat some when starving and throw up when they do. Their fur is rough and unhealthy. I have had to switch to another cat food for them to be okay. There is no point in spending the kind of money that your product costs anymore though I have done so in good faith for many years to the betterment of my pets. Why did you try to fix something that wasn't broken?

I recently bought the Original formula, I noticed my cats stopped eating a lot of it. I got a different bag, the one for cats 1-6. HATED THAT ONE SO MUCH that they only ate enough to survive. Switched back to Original (the whole time I thought I was getting the wrong bag) No! I got the correct one.. they hate this stuff. Both cats hate this newer formula. I also noticed that the bag got smaller by 3 pounds and the new seal close strip does not work well, it keeps coming open and the price is really expensive and it feels like I am getting ripped off!! We were LOYAL SD eaters for 7 years, I am no longer going to purchase Science Diet. Why did you ruin the food? You lost another 2 cat family purchase!

My six year old cat developed a urinary blockage and it was suggested to use Hills CD. I used the wet food and then tried the dry CD for cats. My cat started losing weight/vomiting and was generally tired. He developed diabetes. His blood sugar was 555. Normal for cats is 104-240 I think. I just happened to look at the ingredients on the CD dry food and it had 35% carbs!!! My research began and found out cats should NOT be eating carbs as they are strictly carnivores. Long story short, I feed him a pure meat diet from a cat food you cannot find in the box stores. No more diabetes! It's been 5 months now and I still check his sugar once a month. No problems at all. His blood sugar is normal! He had tremendous energy and his coat is soooo silky. I blame Hill's Science Diet for this. What a racket!

My vet told me 3 cats were overweight (2 were 15 and one is 16 years old) and they put them on this Hills metabolic feline food. They were only on the food for about a year and now one is diabetic and the other has an inflamed pancreas and has to take steroid medication for it. It has now cost me well over $3000 for all the procedures for the 2. Today they are not overweight, but the other one who didn't get affected by the food still is overweight. I do not think it is coincidental that 2 out of the 3 cats are now sick with similar illnesses. They are now off the food for about 8 months and are getting better, slowly. Their food is Go Fit and Free and a permanent diet of home grown barley grass for the enzymes, but they are still sick. Can someone please tell them to do more research on this prescription diet? I am hoping they will survive this. :(

I have been using the Hills Science Diet Cat t/d cat food for ten years now, but in the past two years I have noticed a strong odor that smells like cow manure or some other form of waste when opening the bag. In the meantime, I began to look for other foods to feed my cats. My one cat would only eat the t/d so I continued to purchase, as the odor has not always been consistent until this last year and most recently in September 2015. The odor was so bad that I threw the food away. I contacted my vet to report the food and so they became aware of this issue if any animals became ill. I also contacted Hills but my complaint was not addressed. They only sent a form email back to me. In addition, I reported my experience to the FDA. And I encourage other people to do so as well. It would be awful if any cats became ill or fatally ill after ingesting this food. Thankfully, my cats are well and no longer eat this food.

I always use Hills Science Diet dry food and my cats love it except for the low fat variety! I had to give up using their canned food because there was no variety, sometimes it was so runny it was like liquid and the price is exorbitant. I changed to fancy feast.

Hills has the best dry food for hairball control. However, our cat gets tired of it periodically and we have to augment it with something else. All in all, it's a good brand.

I used Hill's Science diet both canned and dry food for the last 30 years and have not had a problem. They make excellent cat food. The problem now is the cost. I can no longer afford their prices so I have now switched to the Costco Kirkland brand for their dry food and Friskies canned food... just so much cheaper. So far so good. The cats seem to be doing OK.

I feed Hill's Science Diet Indoor cat and have had no issues. My kitten also ate this brand kitten food. Love it! I am a very loyal Science Diet fan. I have researched pet nutrition and feel that Hill's is a good, reliable company that cares about pets and provides a product that you can really trust.

Hills Prescription Metabolism Diet for Cats. I started feeding both my cats this product hoping they would shed a few pounds. For the first two month, I did see some weight coming off. However, my male cat started struggling with his bowel movements. There would only be one or two pieces, and they looked like cement. I talked to my vet, and he gave me some laxative type home remedies (canned pumpkin, wet food), I ran up to the grocery store and purchased a smaller bag of Iams for weight management. I hope this and the wet food will help his system get back to normal.

This is a well made product with few, if any, recalls. It is healthy for my cats, they like it and have never had an adverse reaction to the product.

My cat of 2 years old recently got crystals in his urine and had to get unblocked, so the vet told me to only feed him the Feline CD food to help prevent this from happening again. Anyway, my cat would vomit violently after even eating a few bites of the dry food. Then I tried the wet food, same thing. This went on for a few days and I finally switched him back to his old Blue Buffalo and like magic, he stopped vomiting. I've ordered the prescription formula dry food from another company and will see what happens, but in this case it was clearly the food! Either Hills Science is toxic garbage, or he's allergic to something in it, but my story sounds very similar to what others are writing here! I will NEVER use Science Diet again.

Our 2-year old cat has been on Science Diet since a kitten. 2 weeks ago he started with diarrhea and became very sluggish (he is very active). We notice he was not eating out of his feeder and would meow more for his "Treat" which is half spoon of wet food. We purchased Blue and placed a bowl of the Science next to it. He went straight to the Blue. Whatever change was made in the Science did not agree with his system and he knows it.

My husband acquired a beautiful big 5 year old Tuxedo cat only a month before he passed away. He loved the cat and I love all cats so I wanted to give him the best of care. He weighed 20 lbs when we got him so I asked our vet if he should lose weight. Hills Metabolic Diet had just been released and he recommended it. The cat loved both the wet and dry versions and lost weight rapidly. When he was down to 13 lbs, I stopped using the diet. He looked fine and seemed to feel fine. A year later, he looks like a cat skeleton with a bit of fur over it. He is ravenous and begs for food day and night but it seems to do no good. He had been eating a dry food (not the Metabolic Diet) but began to throw it all up so the vet switched him to Hills I/D wet food, but he doesn't care much for it even though he acts starving.

I purchased a bag of metabolic cat treats at my vet. When I was about to open the bag, I noticed a white fairly large substance inside. Upon closer observation I felt and saw the texture and realized it was gum!! How gross!!! I called the Hills number right away and the guy on the phone assured it was a serious rare case and was sorry and would send me an envelope on the mail so I could send the product back and have it tested. He also requested I take pics and email them to him. I did just that, and send pics from all angles to make sure they knew the package was not open.

I've fed Hills veterinary w/d to my cat for the past 7 years. I notice a change in the color of the same product in the latest bag I bought at the vet in late July 2015. The product had a change in color and color variation. Upon exam on the previous w/d bag and the latest w/d I note the (new) addition of corn gluten meal, wheat gluten among the first 4 ingredients. This may explain why the newer kibble is totally different color yellow with brown spots.

I have recently found ground up chunks of rubber bands in cans of Hill's Prescription Diet K/D formula wet cat food. They were found in both a can of the Chicken flavor and in a can of the Ocean Fish flavor, which was recommended by my veterinarian (purchased on 5/19/2015). I am returning the food to my vet tomorrow and will be informing the company (saved the cans with sku numbers, have my receipt and have the pieces saved in a bag). I will not be feeding this garbage to my pet again. I will be looking for an alternate food for my cat who is in the beginning stages of kidney failure.

My cat was on a strict prescription Hill's food diet (wet and dry) for a Urinary Tract Infection he had 3 years ago. Just recently on May 26 I had to take him to the Emergency Vet Hospital for problems urinating. He is now being treated for another Urinary Tract Infection.

My female Calico best friend has been vomiting her cat chow and I have tried almost every brand trying to find something she can eat. Her doctor suggested Hills ID. The change is amazing but she has damage to her nervous system. I am praying this will get better and feeling awful because I am responsible for this. My other male Calico best friend was also intolerant of commercial cat foods. He is much better now after 3 months eating only Hills ID. His coat shines and he has a smile on his face. Please be careful where the food is stored. The consumer is quality control. Molds and bacteria can grow in improperly stored pet foods.

I have been feeding my cat Friskies dry and can food for 4 years now without any problems. At an annual physical exam, the vet found my cat in good health except some tart. She recommended Hill's t/d (dental health) diet. Since I have switched my cat to the Hill's diet, I have noticed bald patches on her hind leg. After two months, my cat's abdomen and hind legs look like somebody shaved them. She also gained weight.

My cat was prescribed Hill z/d for IBD. It really helped her, so I went online to buy more cans. When the cans arrived, they had a silver tin where the ones I had gotten from my vet had a gold tin. Shortly after giving her the food from the new cans, she got all red all over and would not eat. Hills claims that nothing changed with the food, but when I switched back to the gold tins, my cat went back to normal. Something is not right here.

Hill's Ideal Balance Wet Cat Food - We switched our beloved boy over to this approx. 6 months ago while searching for a healthy new food- specifically we use the slow-cooked chicken and veggies recipe. The ingredients seemed promising and I found great reviews all of the internet on various pet food sites and other reputable industries like Amazon.com. He seemed to love it at first but as of about a month ago, this food has been making him vomit randomly after meals.

Hill's K/D Renal Prescription Dry Food for cats - Has anyone experienced a recent problem with this product? Just bought a new bag and both of our cats are throwing up. This is highly unusual and has not happened in the past. Bag states best if used by 5 2016. We changed the dry food and it has stopped. California purchase.

Our male cat was prescribed Hills CD due to crystal formation. So, we abided by the vet's advice and we fed our cat this food in dry form for years. His health improved on the food. But, after a long time on this food, he started acting strange - throwing up, meowing all the time, letting us know he was unhappy, etc. We ignored much of his behavior for a long time, thinking he had psychological problems. Then he started getting diarrhea and there is nothing like this to get your REAL attention! I called our vet on a Tuesday for advice but she could not talk to us until Friday. No one there could help us so we went online to search for answers.

My cat had a urinary blockage from crystals in his urinary tract. Of course the ER vet prescribed Hills SD and indicated that he needed to be on the diet for the next couple of months. I put him on the food for a few days like an obedient patient, and but then checked the ingredients. I had been feeding my cat grain free diet for the last few months and wanted to ensure he was still getting grain free. Much to my surprise, Hills SD is NOT grain free! Corn is the second ingredient. According to the FDA's website, pet food ingredients must follow the same policies as people food in that the ingredients be listed in order of amount. So the fact that it is the second ingredient means the food is mostly corn and therefore mostly grain!

My cat had urinary problems and the vet put him on cd. He ate it but didn't really liked it. After years on it, he has some issues again. He has allergies and I'm not sure if it's from this food. Did a lot of test, they found nothing. Now he's on zd and he ate it for a while and now he refuse to eat both food. I don't know what to do, I'm very worried and fed up at this point.

Ever since the vet prescribed Hill's z/d for my cat's food allergy trial, his stool has been watery and basically less than ideal. The first day when he was completely on this food, he had diarrhea all over the floor, it was bad. Previously when he was on commercial food, he was not having diarrhea and issues like this. To top it off, he's on allergy trial so we have no choice but to stick with this diet. Has anyone faced this issue on Hill's z/d?

I only wish that I had read this forum a few months earlier. Last year, my 11-year-old cat started peeing outside of his litter box. The vet diagnosed him as having crystals in his urine, and recommended that he switch to C/D food. I did so immediately, and was consistent with this, despite the high cost (about $70 month). He started spitting up on occasion, and then more regularly in the last few weeks. This morning, he started whining uncontrollably, and then laid down and started panting heavily. After many diagnostic tests, the vet assessed this as very probably liver cancer, with the entire liver extremely enlarged, with heavy internal bleeding from multiple spots. He died this afternoon. I miss him greatly, and while proving cause and effect is always tricky, the Hills food seems like a very probable cause here. Another data point suggesting that there is something grotesquely wrong with this cat food.

In October of last year, my lil girl Sabrina (who is 14) was peeing and drinking constantly. We took her to the vets and they diagnosed her with a kidney infection. She was given medicine for that. They told us that her kidney levels showed that she had the on-start of kidney disease and highly recommended the Hill's K/D feline food for her. So we started her on the food. Well, she started having diarrhea. We called the vet and they gave her a probiotic to take. Well, that didn't stop it either, so they suggested Flora to sprinkle on her food. Didn't work. This went on for a while.

My cat was put on CD years ago for crystal formation in his urine. He never liked it. But over time he came to tolerate it. One time I opened a can he wouldn't eat for the entire day. It spilled a little industrial to me. I threw it out and he ate food from the next can. I thought I'd gotten a single bad can and was lucky my cat didn't eat it. Less than two weeks ago, I bought two cases of CD cans (one seafood, one chicken) from my Vet. He won't eat any of it. I've opened several cans from both varieties and he sniffs it and walks away. I was suspicious but after reading these reviews I'm scared. I hope that some of the food I tried to trick him into eating by mixing in other things he likes won't have hurt him. I definitely won't give him anymore. Don't know what to do about food now. But will start researching and give him Fancy Feast in the mean time which he never refuses.

My cat, which is 13 now, has developed an aggressive cancer in her left paw and she has been on Hills Prescription Diet - Low Fat Urinary, her entire life. One thing that made me suspicious about this product is that every single time throughout The years, I tried to take her off this particular product, she immediately started to have blood in her urine, and she went to the toilet up to every five minute constantly. Plus that she refused to eat anything else, for up to 5 days, even though I tried to put Whiskas in front of her. I felt forced to let her get back on Hills Prescription again, feeling powerless of any ways out of it. It seemed crazy to me that this was the only food she could eat. Now she has got cancer and it's pretty bad.

I brought a kitten to the vet because he had some bowel issues and the vet prescribed W/D canned cat food. This was to help reduce the fat in his diet and help stop diarrhea. The kitten has been on this about two months. Since then, he has the worst gas in the world. I stopped it for a couple days and as soon as I gave the food back to him, his gas returned. I am feeding my other cats the same food and one cat started defecating in the bathtub. He never did this ever before. His bowels are now loose and he paces all around like he's more irritated.

I have three cats. Two of whom are elderly and have been eating either WD or KD most of their lives and have devoured their dry kibble. Now that the KD and WD have changed, they are having it! AND someone urinated outside of the litter box, which never happens! PLEASE, don't cut corners. Put things back the way they were. Don't play with the lives of our babies. PLEASE.

I've been feeding my three cats the K/D dry food for over a year. I purchase the food from my vet and transfer the food into an air-tight, screw top container so I didn't have the bags to compare nor do I have any way to compare the expiration dates. About three months ago, when I transferred a new bag I noticed that the kibble was smaller and a much lighter color. There was nothing on that bag to indicate the change but on the bag that I bought this week I see a notice of change of shape on the bag.

Several years ago I put all of our cats on the Hill's Science Diet C/D dry cat food after one cat developed a urinary blockage (We switched to regular clay litter from clumping too since our vet said some male cats can develop urinary blockages from the gel used in clumping litter...they ingest the dust when they groom themselves). We have always had issues with them throwing up this food, but we attributed that to maybe gorging themselves when they ate... We just weren't sure. The number one reason we liked this food is that there was always very little waste in the litter pan, which was nice.

My cat Niko was *exclusively* eating Hills Z/D, as recommended for chronic herpes. He developed renal failure and died during the melamine contamination scandal. Hills refused to take any responsibility. As this occurred in 01/07 -- when I did not think I had any recourse -- I doubt that a suit would/could do anything; however, if someone is interested in taking this on contingency, that would be fine with me.

One of my cats was diagnosed with a single small kidney, which is an early sign of kidney problems. We have two cats that both got bad diarrhea from a bad batch of canned food, and replaced it to heal them. After the diarrhea was gone I bought some Hills prescription K/D canned and dry food for my one cat with kidney problems. Lo and behold, the diarrhea is back, and just for her. I'm thinking maybe it's a relapse, but we alternate the dry and canned food, and she gets diarrhea every time she eats the canned. There is something wrong with Hill's canned K/D feline food. Don't give it to your cats.

I have been feeding my cats Hills prescription diet C/D since early summer 2010 as I have one cat with urinary problems. All has been ok and they like the dry as well as the wet food seafood flavor. However, the last bag I bought on 11/29/2010 is, I believe, poisoning my cats. My older cat began having intense "skirting" diarrhea and vomiting. I just thought she ate one too many pieces of chicken. She loves table scraps and has been eating them for years with no problems. I called the vet. The advice was go without food for 24 hours; if she is not better, bring her in.

My cat of 9 years contracted a skin allergy in December 2008 (possibly from being allergic to Whiskas). He has been in and out of the vet since as he seems to have a food allergy of which we are still trying to pinpoint which foods. I know lamb is a culprit. However, he was on the Hills light (chicken flavor), which did not help with the allergies. We then tried the d/d diet, which meant he threw up almost every day - the last week of the food, it was every day. His vet suggested I try Iams and he seems okay on it, though it has only been 10 days. Because he swallows the small pellets instead of chewing, I asked my vet if there was a Hills product with bigger pellets so that he can chew his food and seem less hungry. The d/d diet had big pellets and he seemed to get fuller quicker and not be hungry all the time. She suggested I try the t/d diet. It lasted two days and he was throwing up on it.

I had two beloved cats become ill in the same weekend. I had to put them to sleep. They both ate the same food so I have become suspicious and cannot find enough information to have the food tested. Both cats were put to sleep at a cost of $500.00. And the hell I went through emotionally there can be no dollar amount on.

In the fall I wrote to Hills Prescription Diet regarding their MD wet and dry food. I could see my cats reacting to it and I wondered if they had changed the formula. I wrote to them and asked them if they were using any new or inferior ingredients. They wrote back assuring me everything was top quality. Now I find out it was not. This is very frustrating as my vet insisted I feed them this very expensive food as they were overweight. I think this is a real scam and that they have done a remarkable sales job on the vets who are heavily pushing this MD food as atkins for cats but it a lot of money for garbage. I wish I had stuck to my guns and just kept my cats off the food and hadn’t bowed to pressure from my vet who thought he was doing what was best.
