Hills Cat Food Reviews

I'm glad I found it before my kitten did.

My three cats (ages 1, 5 & 7) all eat Hills Prescription C/D Urinary Care cat food and are healthy, active and happy cats. Only one needs it, he had a urinary tract infection and the vet suggested this food. But the other two cats won’t eat the other food anymore (they love this stuff) so it's our only cat food now (both wet & dry).

I had 5 cats, one had cystitis so vet put him on CD feline prescription food. Gave it to all my cats. Caused runny poo in 3 of the 5. Was on autoship with Chewy.com. The cat that it was prescribed the food passed away before I could cancel the final food shipment. Opened that bag last week and I noticed my cats ate less and less daily. Two of my cats started vomiting with diarrhea this past week. The only change was the new food bag. Apparently it is tainted. Chewy will refund the money and was given a reference number and a telephone number to call M-F during business hours so I can speak with a Hills representative. Going back to the vet tomorrow since one of the two cats is still ill. Not a fan of this overpriced product!!!

We listened to our vet and put our cat on the C/D formula food after he had urinary tract infections and the vet told us he had crystals in his bladder. At first things seemed to go fine. We switched him and our other 2 cats over to the C/D food from our previous brand. We dealt with some MASSIVE hairballs and a little bit of throwing up of the food but we switched them directly over and didn't transition them due to worry about the one cat's health. We asked the vet about the hairballs and vomit and he said it can be normal when switching food.

Both of my cats were put on Hills CD for crystals in their urine, one cat consistently vomits her dinner up a couple of times a week, the other has now been diagnosed with kidney and bladder stones, calcium in origin. Researching this food I have seen issues with the CD diet creating too acidic of an environment, which then creates calcium (kidney) stones, also all the corn products produce oxalates, also increasing the incidents of calcium stone formation. I do believe this food is garbage, evident in the dozens of dead flies I pick out of the bags. I have never purchased any animal food in all my life that literally has dozens of dead flies in it, I guess they can increase the protein content on the label now. Will not be purchasing any more Science diet brand foods anymore.

For many years I believed the commercial pet food companies and I killed all my pets. Then I did some in-depth research. After I finished crying, I started to feed my beloved friends differently. It was difficult and expensive yet worth it. You would not feed a human baby potato chips and other junk food. Do not do it to your pets, especially cats. Cats are obligate carnivores - peas, carrots, wheat, barley, etc. are useless. Cats eat grass to help them vomit hair and fur, and void bowel matter, not for nutrition. Vets sell this stuff for two reasons: 1. They make a bottom line profit; 2. The animals get sick and the vets get more business.

My cat transitioned to Hill's ok, but he often won't finish it. Odor is awful to this human. Also, food variety is sparse. But it has seemed to help his urinary problems.

All 4 of our cats eat some version of Hills Science Diet prescription foods. We are very happy with the product and we believe the foods are helpful in keeping them healthy.

I feed my 8 year old Maine Coon Hills c/d kidney because he needs Special food. O'malley Cost us $2000 in doctor and surgical bills for sort of what I called kidney stones or granules/grit in his urinary tract. He loves his Hills c/d and I feed him wet and dry. We buy the food at PetSmart. He has lost some weight and recovered very well. Hills seems to be very good. I purchased Hills through my vet at first making it a bit more expensive, but now I have a prescription to go to PetSmart to get his food, Hills c/d Kidney. He was never a finicky cat and always ready to try a new brand, but now we only do Hills. It is what the Doctor ordered!

Hills Cat Food was recommended by our vet for our new kitten. I feel confident that the ingredients are of high quality and the taste is great for our kitten. Our kitten just gobbled it without questions either it’s a dry or wet food.

My cat had a blood test three month ago for regular routine check up, with BUN 71 and Creatinine 1.9. My vet suggested to change the food to Science Hills k/d and rechecked three months later only finding BUN to 169 and Creatinine to 6.9, getting worse. After treatment with daily fluids and change food to Royal Canin for about a week, the result of those two index still remained the same. So my vet suggested to put her away last Sat. I just cannot believe what went wrong, the only change we made was to change to Scientific Hills' k/d food. I am so upset about that. Hope this will help people when they want to change food for their beloved cat.

My cat went on Hills Science Diet c/d after having urinary tract infections that started in 2010 when I got her. She never had one when she was on the diet but if I went off they would come back. She would get bored with the wet food so finally I switched to Fancy Feast wet food and Hills c/d Dry food which she has been on for about 3 years with no issues. A few weeks ago I took her into the vet and she was diagnosed with an oral tumor which grew so quickly she needed to be put down yesterday. It's called Feline Squamous Cell Carcinoma. An oral cancer. She was 10 years old and an indoor cat that was well taken care of. I don't know what caused this but am concerned if the food had any impact and it seems like regulations are lax. Sharing this in case it's happened to anyone else.

My cats have been on Science Diet Senior (7+) Hairball Formula for 10 years and it was like CRACK to them -- by far their favorite. Suddenly, with the new bag, they are very disinterested in it. In fact, they won't eat it. Same with the Adult (Ages 1 - 6) Hairball Formula. Even my outside cats, who will eat anything, and the POSSUMS won't eat it. I called Hill's and was rather rudely told that each batch is tested and it must be the way I store the food/gave it to my cats/some other external reason that they quit eating it. I have 12 cats. And they used to love this stuff. I don't care what their testing revealed, I know my cats and when they quit eating something en masse, there's an issue.

Please pay attention to your kitty if feeding the wet C/D prescription food. My cat was on this food for 10 years therefore I did not notice the decline in her health immediately until we went to the vet and they told me that she had lost a pound. I started monitoring her like a hawk and she begrudgingly was trying to eat the food, she started scratching her face till it was a big bloody scab and her hair was falling out in clumps. I switched her over to Wellness 3 months ago (she only like the Pate) and she is like a brand new cat that is not being poisoned. Her weight and energy levels are up and her skin and fur are better than ever. The vet ignored me when I told them there was a problem with the food and I was taking her off it ASAP.

I recently bought my second bag of the Science Diet Indoor Age Defying dry cat food. Prior to that I had been using the Nulo brand, but thought I would change things up a bit. Yesterday, one of my indoor cats was throwing up his dry food non-stop (it comes out yellow, and nearly in whole bits). My other cat who is his sibling, had a seizure!! Her legs went out under her, and her eyes starting moving back and forth, then her head started to do the same! We rushed her to the emergency vet. The vet said that she was nauseous (she was salivating a lot), so they gave her something intravenously to help. She is better now, but I am convinced that it had something to do with the food! Needless to say, the first thing we did when we got home was throw away the food. Please watch your pets closely when they are on this food.

Hills Science Plan for Young Adult Cats - I have been feeding my cats Hills food and I'm devastated at what I'm reading about it. My vet has stopped selling it but won't say anything about it when I told her about my concerns. She's the reason that I use the food as she told me it was the best for my cats. One of my cats always threw up every so often and the vet said it was hairballs but I never saw a hairball in what he threw up. Now he's having bloods taken tomorrow and I'm worried sick about it. I'm waiting for other food I've ordered online to come, and I don't want to give my cats anymore Hills but I don't know what to give them in the meantime. Please help! Can anyone give me any ideas on what to feed my cats until the ordered food arrives?

I had 3 kittens without mum. 3 weeks old. I was bottle feeding them and start giving Hills canned food but they did not like to eat them at all. And every time after eating food they start threw up. And start noticing they having diarrhea. Took them to vet few times and they couldn't find the problem. 3rd time they have told me it has to do with the food they eating. So I change the food. And they start getting so strong and playful and they love to eat the new canned food. I have more than 30 cans of Hills food which I have throw away. I thought kittens will die the way they were, thank God they still alive. I will never use Hills products ever again. I saw the vet they selling Hills brand also. Most foster care use Hills Brand. They did nothing to help and totally stood behind the Hills brand when I told them. Please ban them selling this pet food.

My cat was fine. FINE! Ate a lot. About 8 days ago, she had dental surgery and was kind of wiped out for 24 hours but then ate again and was walking around. I took her in for a follow up and the doctor mentioned she had elevated kidney (something the other doctor failed to tell me before I got her teeth cleaned). She gave me samples of Hills. After the second can my cat threw up and started acting funny. On the 3rd day I knew something was wrong (she is an overeater but was eating zero food) and took her in. They took new blood tests and she has intense pancreatitis. I am blaming Hills. My poor little baby is dying or at least it feels like it. Am horrified, depressed. LIKE WHAT HAPPENED? They pulled the Hills off the shelves. I think she was poisoned by this food. I plan on getting to the bottom of this and hope to heck I do not have to call a lawyer but am mad and very very upset as you can imagine.

I was told my cat was overweight. I had been using Hill's dry food for about a year but changed to Hill's Metabolic. After 3 weeks he was drinking a lot of water and urinating a lot and was very unwell. I took him to the vet who I told I thought it was the food. No way. He did a blood test and I was told he was diabetic and he was put on insulin. Ok for about a week and a half, after that he was extremely hungry and was not well. Took him back. Another blood test done and he was low sugar. Very ill. Told to take him home and give him food. This was repeated again 3 days later. He has now been taken off insulin. Within a week he has improved immensely. Cat humans need to be aware of their gut instinct especially where Hill's cat food is concerned.

My veterinarian prescribed Hills K/D Prescription Diet kidney care dry cat food for my female cat. I selected the chicken flavor. My vet told me it would be OK to give this to my male cat as well. The cats loved the food. However, my female cat started itching constantly and losing her fur around her face. The vet said it had to be a problem with the ingredients in K/D. She recommended a hypoallergenic dry cat food, which she didn't have on the shelf. I threw out the remaining K/D and my cat immediately stopped itching. My male cat had no problem with the K/D. However, he has been vomiting often for a while. I wonder if the vomiting has something due with other food I give the cats.

We fed our Tabby Hills CD due to crystal issues for years with no issues... he was super healthy and had no crystal problems. We noticed the canned food changed in both texture and overall appearance. Our boy instantly refused to eat it... prior to this he love it and would beg for meal time. So it was very odd to have him refuse food. What little he did eat he soon after would cough, vomit and froth from the mouth. My mum's dog also notice a change in the cat food. Prior to the new batch of CD he loved the kitty food and when he visited would do anything to get it... he sniffed the new CD and totally refused it. After seeing that a dog would not even eat it we ran to the store and started feeding a different brand. Kitty went right back to begging for meal time and stopped the frothy vomiting. I will never use Hills products ever again. Our vet did nothing to help and totally stood behind the hills brand.

My cat had surgery about a year ago for kidney stones. The vet recommended the Hills science diet urinary canned cat food. I have been purchasing it from the vet ever since. My cat is not fussy and will eat whatever I give him preferably canned food. I also buy Hills dry food for grazing. I returned a few cans in the past as they were seeping at the top and when I opened them the contents were black. Last week my husband and I both noticed that the cans were watery with hardly any substance. I am not happy with this product and feel I should be able to purchase a good product over the counter as long as I read the label and see the byproducts within.

Hill's Prescription Diet Feline z/d Skin/Food Sensitivities - This is super expensive food (fine mousse in tins), but the cats won't eat it. I have tried mixing it in (small quantities), they still won't eat it. I purchased it online and now have to send it back at my cost.

Our cat is overweight and because of this she occasionally flares up of what the vet refers to as "diaper rash". Her butt becomes red and sore. Our vet suggested that we change her diet to Hills D/D skin sensitive to see if her problem was coming from the food we had been feeding her. We agreed and began feeding her D/D hard food. After about 6 weeks on this food we noticed a significant weight gain. We fed her the amount indicated on the bag - and pulled the food up once she had eaten.

I had 2 cats. The older girl was almost a year and the other, a boy, is about 4 months. We had been feeding them Hill's science diet for indoor cats. The kitty had some smaller food but seemed to like the science diet as well. However the kitty started throwing up after eating it and we couldn't figure out why. We thought maybe he was overeating or eating too fast. After awhile it seemed the kitty still had some trouble but older one seemed to not have any issues. Though we had seen blood on their noses before and we assumed it was from them playing but I'm wondering if there were showing signs of poison before. It's a very hard thing deal with.

Cat with IBD has been successfully treated with ** for a while. She's gone more than a year without any significant bowel or vomiting issues barring the occasional small flare up. Along with that she has been eating Hills' Science Diet I/D food as 50-75% of her diet. It was great for a long time. Healthy and tasty because she ate it all up and was doing great. Only exceptions: A couple of months ago I gave her some fresh (new package) dry I/D as usual when I was gone overnight one night (Longer than that she gets a cat sitter and her normal wet food). This has never been a problem as anytime I am gone for just a night this is the routine. No pain or diarrhea usually. But this time, when I got home, she was in pain, had at least a pound of diarrhea in the litter box overnight! (Ok I didn't weigh it but it was a lot!) And scoots all over the floor, and was lifting her hind leg, screaming and unable to sit right. Never seen her in such pain.

My cat's health has declined since feeding him your "not" healthy food. I have already spent over $800.00 getting him better. I told my vet that I believe it to be the z/d diet. He said not to discontinue it after I went in for the 5 to 6 times. I asked for another vet and got very loud to fix my cat. I then took my cat completely off all the z/d and it's been at least a month and a half and is getting better each day!!! I will NEVER purchase your product ever again!!! Oh and I know about you guys previewing complaints and not posting them. So don't be deceiving or I will go further with my complaint!!! I do feel that Hills should reimburse me for all I had spent to get him better. I live check to check every week so this was a very heavy weight on my shoulders but my fur baby means the world to me and I feel like your product almost killed him.

Sorry this is long, but the story has unfolded over the last 7+ months: My cats with inflammatory bowel disease had been doing very well on Hills prescription z/d canned food for over a year, when without any warning, Hills changed the formula of the food. Suddenly, the cans just said "improved formula" on them... With no forewarning that anything was about to change. I realized something was amiss when I opened the first can of a new case of this "improved formula" and a) it smelled horrible and b) the texture was weird, gloppy. I checked the date on the can to make sure it was not spoiled, and then realized it was an "improved formula". Fortunately, I still had several cans of the original formula available and I promptly opened up one of those cans and tried to transition my cats over a 7 day period to the "improved formula".

I have a pet sitting, dog walking business and I am constantly horrified at the number of people who feed "Science Diet" because their vets have told them this is a healthy diet for their cats/dogs. It doesn't take much to tell that the fillers and content in their products are NOT healthy and although cats and dogs can live on the food (like some people can live a lifetime on junk food) it undermines their general health and shortens their lifespan. The fact that vets get a kickback from Hills and Purina (a whole other story) is unconscionable. Vets traditionally know little about pet nutrition and it takes research to develop a knowledge of what is healthy or not. Corn is not. Carrageenan is not. Wheat is not. Chicken by-product meal, Brewers rice, and neither are preservatives.

I have a mixed tabby that is 4.5 years old. I've had him since he was a kitten and in his 4.5 years of life, he has never had a problem with allergies, foods, etc. In fact, he has never turned down any food and was a bit overweight the last time I went to my vet, so I was recommended to put him on the Hills Metabolic Diet in chicken flavor.

I think it is good for our cats, but it is very $$$ and I can almost "never" get coupons for it, and I have to go to the vet or tractor sup to get it or go out of town over an hour drive to a PetSmart, or get online. "Again it would be nice to get coupons from time to time."

On 10-28-16 I contacted Customer Service at Hills Science Diet about the dry cat food that my cat has been on for a number of years. He has Irritable Bowel Disease and was put on the i/d Formula (dry and moist food). It had made a big difference in his bowel movements. He was not going as often and it made his stool firm instead of diarrhea. Several days prior to Oct 28 he was having diarrhea several times a day. I happened to notice, in small print, on the new bag of dry i/d "Improved Formula and New Kibble"... which is why I called Customer Service.

My vet recommends the Hill's cat food. My 6 cats just love it. The kibbles are sized small enough for all ages. The cats do not eat as much as the lower priced foods making Hill's Science Diet a great deal for the money.

My cats are on the Hills Prescription k/d chicken flavored dry food. All 3 love it, but won't touch the seafood flavor. It's really expensive, $25 for a 3 lb bag. Also, they've been out of it for a month or so.

Both my cats have enjoyed the food. They always eat plenty of it but do not gorge and self on it. They have healthy coats and bowel movement. I have been very pleased with the result keeping the cost of the product in mind.

My vet recommended it. I have been feeding my cats this brand for 12+ years. I have been able to move to a different formula as my cats have aged and their needs changed. Their special formulas tend to be expensive so I do feel like they inflate the price. It is harder to find the specific formula I buy so I have turned to buying it online which is saving me money in the long run as I don't go to PetSmart as often and spend extra money. The company seems to rebrand/repackage quite a bit which can be confusing at times.

Science Hill brand has various foods for various issues your darling cat(s) may have and that's what I like and my 3 cats love about it. It is a 100% quality product for sure. I just wish the price were a little less and also that they made a 32/34 or 36/pack set. Overall, it's an A+ product.

Hills changed their formula for their z/d canned cat food a couple months ago and our cats will not eat it. We have a special needs kitty that requires this special formula so our other two cats eat it as well. They LOVED the old formula and I've wiped out the shelves that still carried it. They will not touch the new formula and I had to return many cans to Pet Smart. Now I'm out and I don't know what to do!

After eating T/D Science Diet one of my male cats became very ill. I noticed he wasn't behaving like himself but he had just been to the vet for a regular visit in the past few days. I started feeding him T/D Science Diet. I thought he was stressed from the vet visit that was just a routine checkup. Approximately seven to ten days later he was vomiting, no bowel movements, abnormal vocalizations, dehydrated, and lethargic. I rushed him to an emergency vet hospital to find that he was constipated to point of obstruction/impaction.

I don't usually take the time out of my packed day so that I can post online, but I am frustrated with all of this "Hill's bashing"! We have MULTIPLE cats (and I have a BS in Human Nutrition) and will ONLY feed Hill's products to our cats. While I do not discount people's pain when they have sick animals, I do want to post a voice of reason. Don't trust all of these terrible posts as valid/legit - they are mostly/probably competitors who want to damage this company (P.S. Happens in Washington all the time! Big PR agencies are hired to "hurt the opposition"). Our rescues have longer fur, are healthy (one is a senior) and have been eating Hill's Ideal Balance and also Prescription Diets for YEARS! They are the GOLD STANDARD - and others do not even come close to the high quality of Hill's foods. Ask your Vet what THEY feed their animals - and then decide for yourself!
