Our rescue cat had numerous lesions when eating normal cat food, no matter which brand we fed him. Our vet put him on this product two years ago, and the only time he developed those lesions again was when we experimented with non-prescription food. Fortunately he hasn't gotten those lesions again, but at $60 for a 7.7 pound bag, we have "lesions" in our household budget. Good product, unreasonably high price level.

Finally quieted his tummy


from Texas

Verified Buyer

My kitty had a severe onset of vomiting that lasted for several weeks, and after an ultrasound, was suspected to have IBD, due to inflammation seen on the test. After a few weeks on this food, he FINALLY settled down. I just wish there was a canned version, as he really needs to lose weight, but I fear taking him off this product.


Love this food!!


from Los Angeles, CA, United States

My 6 year old "Teacup" Maine Coon developed (or was diagnosed with) Food Allergies around 5 months of age. I spent the next 2 years fighting my vet (trying holistic diets, raw diets, obscure and hard to find diets) because I wasn't going to support the 'big evil pet food company who's just paying the vets off anyway'. Finally I broke and tried the Select Protein PV and PR diets. They worked pretty well for him (and saved my 15 year old cat's skin, but that's a whole other review). He still vomited a few times a week, but it wasn't a fight daily just to keep food down his throat. Recently my vet noticed crystals in his urine and suggested we switch to the Urinary SO. I freaked out because of his food allergies and she introduced me to the Hydrolyzed diet (which comes in a Urinary SO + Hydrolyzed). He hasn't thrown up since switching (except for when he gets a hold of my other cats food). This is a game changer. He's put on a little weight and looks so much happier. He still begs at meal time, but now it's not all the time nor is it this pitiful meow that screams "I'm so hungry". Thanks RC, you guys rock!!

Without this dry food my cat would not have the quality of life she has, thank you! [This review was collected as part of a promotion.]


My 11-year-old Exotic ...


from Gresham, OR, United States

My 11-year-old Exotic Shorthair had been on Hills c/d formula for a couple years, having been previously diagnosed with FIC. Everything had been going well, when suddenly she started having issues with vomiting. At first it was just every so often and I didn't think much of it; she has a very thick coat and sheds a ton, so I assumed it was probably just an occasional hairball. Eventually the vomiting started increasing in frequency, and got to the point where she was doing it sometimes 2-3x a day. She also began having occasional urinary accidents outside the litter box again. I knew then that something was wrong. After taking her to her Veterinarian and doing various tests, finally an abdominal ultrasound showed some swelling/enlargement of part of her small intestine. The Vet felt that it was a 50/50 possibility of her having either irritable bowel disease or intestinal cancer, but that without further diagnostics (another ultrasound and a possible biopsy later to confirm), it would be difficult to get a definite diagnosis. Not having the money at that point to continue with diagnostics, I opted to try treating her as thought it was the IBD that she had. I was told about the Hydrolyzed Protein food and also given a couple different medication options that I could try along with the food. It has been just over 2 months since I started her on the HP diet and she has made what seems to be a complete 180 just on the food alone - no other meds! She has not had any vomiting since the first week I started her on it, even her coat feels like it's in better condition than it had been. I also love that it has the S/O index in it to help prevent the bladder crystals she was on the Hills food for. Her Vet said that based off of her response to the food that the chances of her having the intestinal cancer had dropped significantly. I'm relieved, I know she feels much better, overall a win-win situation! [This review was collected as part of a promotion.]


Works wonder for my cat!


from Burnsville, MN, United States

My cat, Gato, has had a sensitive stomach his entire life. He used to throw up his food after meals at least twice a week. I tried countless other foods, including grain free options. Thank goodness I found this cat food. As soon as we started this food, he stopped vomiting. He loves the food too, and I love the vomit-free aspect! I would highly recommend this food since it's a great fix for a cat with a sensitive stomach. [This review was collected as part of a promotion.]


Great for sensitive cats


from Mexico City, Mexico

I bought this two years ago for my Devon Rex cat with allergies. He is doing great on this food, and his non-allergic sister loves it as well. Helps with digestive and skin issues due to allergies, and is a great elimination diet to rule out allergies. It is well worth it!


it works and Pretty likes it


from Oregon, United States

This product is expensive, but it works and Pretty likes it. Helps to curb the episodes of kitty puke from her IBD. [This review was collected as part of a promotion.]


Our cat Hurley has been ...


from Hamilton Township, NJ, United States

Our cat Hurley has been living on this food for almost four years now. He was diagnosed with inflammatory bowel disease nearly five years ago, and after trying several alternate-protein diets, we finally found that this Hydrolyzed Protein formula (along with prednisolone) keeps his intestines working, and he enjoys the taste enough that he does not seem to mind the lack of variety. The only problem we've had since he's been on this food is that he developed another urinary tract blockage, since he needed to stop eating Royal Canin Urinary SO formula, so he needed to have surgery to prevent further urinary tract problems.

Both cats like this food a lot. I also bought the auto feeder I think we are on our way to getting the weight under control finally. We will see in about 6 months to a year.

Small easy to eat kibble


from Simi Valley, CA, United States

I bought this at the recommendation of my vet for one of my cats with digestive complications. All five of my cats love it & prefer it over any other dry food. The kibble is smaller in size and easy for the senior cats to eat. [This review was collected as part of a promotion.]
