Royal Canin Veterinary Diet Hypoallergenic Hydrolyzed Protein HP Dry Cat Food Customer Reviews

Royal Canin Veterinary Diet Hypoallergenic Hydrolyzed Protein HP Dry Cat Food 4.6 5 33 33
Our cats are feeling MUCH better! We have two cats who were having stomach issues, vomiting regularly. Our vet told us they were both having problems digesting the food we are feeding them. None of the other cats are having a problem, so it is a particular issue with these two, ages 2 and 13. Our vet recommended we begin feeding Royal Canin Hydrolyzed Protein to both Lacy and Vincent. They have been on the HP for about a month now, and are doing so much better. And they like the dry cat food! Not often the case, especially with cats. There has been no vomiting, and both are gaining weight, as they are able to digest the HP and keep it down. We got our first bag of HP from our vet; since it's so expensive, I began an online search for a less expensive place to buy it. Chewy was it! Both of our little furballs are feeling great, and we are saving a little money, which is always helpful. Thanks, Chewy! August 10, 2013
A lifesaver! After a year of serious and distressing problems where our cat was not able to digest her food (vomiting almost daily), we finally tried a diet strictly with this formula and our cat's life changed. She's been problem-free for over 3 years now and we owe it completely to this food. We had tried other diets but this is the only one that worked. Highly recommend it for a cat with similar issues.

I think this product saved my cat's life! My vet and I had tried everything to try to cure my cat of diarrhea.He suffered from this for a full year. As soon as we put him on this cat food, it went away. YEAH!!!!! June 28, 2013
Special Needs Kitty WSU in Pullman, Washington recommended this to my Vet, Frankie (kitty) she was having terrible soft pooping problems. Thank goodness for tile floors... She has been on special foods for several years now and never had problems then all of sudden Problems... so after a year of cleaning up behind her we tried this diet and within a week her stool firmed up. She is now about to try the soft food too since she has no colon and her system does not create enough water for her stool. I found her starving 10 years ago, her tail and hip broken. Its been very challenging for her system has changed over the years but she is a sweetheart. The only negative is the price hope Royal Canin gives out coupons once in a while to help with the high cost, I am in my 60's and would like to retire... Just a note when a few years ago a lot of the foods had pets sick and dying from an ingredient they purchased from China, I was feeding Royal Canin and they were one of the few manufacturers who did not buy from China. High quality all the way. January 22, 2013
Both my cats with sensitive stomachs will eat it. They rarely throw up as it seems to agree with them. I had a hard time feeding them food that did not upset their stomachs. This helps so much that I will continue to buy it. Just wish the price was a little lower. September 22, 2013
Great product solved scary pancreatitis episodes. Our 6 year old Birman Gracie had two episodes of what appeared to be pancreatitis. We were on a hairball control food, dry. Our wonderful vet suggested we put Gracie on the Royal Canin. It has been wonderful. All 4 cats, ages 3 - 14 are on it and all are doing great. We also had vomiting on a weekly basis from somebody, they took turns! Hardly any vomiting anymore and that was a weekly thing. Life is better for everyone. November 22, 2014
Not one of my 7 cats will eat it I have tried for three weeks to get any of my cats to eat this, and still have 1/2 of 8lb bag I originally got from my vet. I have no idea what I will do with the 20 lb bag I bought from you. They would rather starve! May 11, 2013
This food has greatly improved our cat's digestive sensitivity Since we began using this cat food our cat has had far fewer incidences of gastrointestinal problems. The hydrolyzed content of this food has helped her pass food through her system more easily. September 28, 2014
