Hills Cat Food Reviews

In February I transitioned my 6 year old cats from the ‘Indoor Kitten’ to ‘Indoor Adult 1-6’. The packaging states “For digestion, immune system and organ health”. I didn’t know until today that his was the cause of their frequent vomiting of their still mostly formed food. After an emergency visit for all three of my cats to a vet hospital due to vomiting water and bloody urine, and scans showed their intestines and colons were backed up with hardened poop which resulted in enlarged bladder walls and enflamed colons. They all required emergency enemas and IV hydration.

They have apparently made changes to the digestive care formula. Before the change my cat could go on this prescription food and after a few days her stools would be normal again. But not since the change. Now she can’t even make it to her litter box in time before she has diarrhea.

We have been feeding our two cats Hills Science Diet Urinary Hairball Control, both wet and dry, for 12 years. The last bag of dry food I purchased it was obvious something had changed, the kibble was a different shape, size and texture. My cats began eating the first bowl and instantly vomited RIGHT BACK INTO THE BOWLS. I did a little research and found this is a common problem with the new formulation. ARE THESE CAT FOODS EVEN TESTED? Very disappointed in Hills, I thought this was a brand we could trust.

I've been feeding my cats the dry Hills Science Prescription Urinary c/d Multicare for years. I got a new bag of food late December 2025, noticed it looked different. Then my female cat started getting sick vomiting and not eating. $400 later with blood work and good report. Now my male cat is vomiting, staying under the bed, won't touch his food. After researching, I found this to be the case with many cats. Hills changed their formula October 2025, and DID NOT let anyone know of the formula changes. SHAME ON YOU HILLS and GOODBYE forever. Thanks for putting us all in a position where we have to be concerned with their Urinary issue while trying to find and slowly transition into a new food.

Please, think twice before giving your cat Hill's Prescription Diet k/d. I don’t know exactly what is going on with the current formulation or why it’s being recommended so broadly, but I can honestly say it is not working for my cat. In fact, it has caused a complete health setback. The most alarming part is that he now has persistent, severe diarrhea—a problem he has never had in his entire life. Before starting this specific food, he had a perfectly healthy digestive system and zero history of stomach issues or sensitivities. Since the switch, his quality of life has plummeted. It is heartbreaking to watch a pet who is already dealing with health challenges have to suffer through gastrointestinal distress on top of everything else.

I know there are people whose animals have gotten sick with this company because the wrong food was put in a differently labeled bag or can, but for OUR kitties things have actually gotten much better since we switched them away from Friskies and onto this food. Their weight is recovering, their coat is shinier, and the vet said their blood pressure has been in range and stable.

Have a cat that has IBD. I purchase Hills Science perfect digestive food. Whenever I shop either online or at the store they show pictures of pate as chunk food. My cats hate pate and will only do the chunk wet food and three times I have purchased pate based on the pictures on the food. I know this is really on me, but I am new to needing cheater glasses and don't always have these when shopping. To me the picture of the product should represent what I am buying.

This wet canned cat food hardens like concrete when I put it on a small plate for my cat. I can't imagine what it does to the cat's insides. I have to scrape off the remainder bits with a sharp knife because I do not want it going down my kitchen sink pipes. Better off making your own homemade kidney care where you can pronounce the ingredients.

Hills Science Diet causes my cat to vomit every time she eats it. I talked to another lady that fed it to her cat and she said it made her cat sick also. So don't buy if you love your kitty. I was using the wet cat food. I was thinking that maybe she was vomiting hair balls, but it was just food. No hair. It gave her loose stools, if she was able to hold it down. I gave it to her several times until I realized it was the food making her ill. She will be a year old in a month.

I've been feeding my cats the sensitive stomach, they loved it until they changed the size from small round giblets to larger flat size, my cats DO NOT like it, and have a hard time chewing it, disappointed, they need to change it back.
