Customer Ratings & Reviews

Rated 4.7 out of 5 by 80 reviewers.
Rated 5 out of 5 by Good experience ordering Royal Canin Veterinary Diet Hypoallergenic Hydrolyzed Protein HP Dry Cat Food My vet authorized the purchase of Royal Canin hydrolyzed dry cat food to spare me a 50 mile trip to get it from the veterinary clinic. The food came quickly and the price was good. All of my cats enjoy it, in addition to the one who needs it. My cat Henrik accepted the delivery in great anticipation (see attached photo). May 14, 2016
Rated 5 out of 5 by All my cats like it! This food is being prescribed for my cat, Alexander but my other three cats, Oliver, Chester, and Louie eat this food, too and like it! A great adjunct to the Urinary So dry cat food that Alex needs also, for his urinary tract health. May 9, 2016
Rated 5 out of 5 by Great product I fostered then adopted my cat from the local Humane Society. She came in as a stray, very underweight with severe hair loss. This food addresses her undetermined food allergies and, as you can see, she is thriving on this diet! May 6, 2016
Rated 5 out of 5 by Throwing up Resolved My 10 year old calico cat started throwing up on and off for the last 2 years. It would happen after eating, sometimes just phlegm. Took her to 3 vets, X-rays, ultrasounds, blood tests, etc. Finally took her to a cat only doctor, she recommended this food. Took a few weeks but finally she is back to normal. Doesn't throw up or put her noise up to her food even though she was so hungry but just could not eat. She must have food allergies. This food I feel has saved her life. ❤️ September 17, 2015
Rated 5 out of 5 by This product has done wonders for my cat Lexie, my 12+ yr old was throwing up constantly, needless to say I was getting pretty worried about her. Nothing I tried worked. I finally took her to my wonderful vet who recommended I put her on Royal Canin Diet Hypoallergenic Hydrolyzed Protein Adult HP Dry Cat Food. I was apprehensive she'd even eat it as most of the veterinary cat food I've gotten in the past has not been appealing and getting my cat to eat it has been near impossible. Amazingly she loves it! I also put my other cat on it to make feeding easier and she loves it too! No more throwing up and she has finally put on some weight. We're ALL much happier!! September 13, 2014
Rated 5 out of 5 by 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
Rated 4 out of 5 by Takes a little time to work but works great! Skin issues heal quickly. Just keeping her on it for the long run and I am confidant that she will stop scratching eventually! April 24, 2013
Rated 5 out of 5 by The one food our cat can eat. After a lengthy and ultimately fruitless search for a meat-based protein our rescue cat Loving could eat, our vet diagnosed her with a meat-based allergy and prescribed Royal Canin Hypoallergenic Hydrolyzed dry food. Now she's regaining her health and energy thanks to Royal Canin, our vet and Chewy for carrying this very expensive product at a much more reasonable price. Likewise, thanks go out to Chewy's RX team for facilitating the purchase of this prescription food. May 15, 2016
