Rated 4.7 out of 5 by 65 reviewers.
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 5 out of 5 by 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
Rated 5 out of 5 by 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.

Rated 5 out of 5 by 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
Rated 4 out of 5 by All 4 of our cats love this cat food! We have four cats and one of our long hair cats had allergy issues for the longest time. The vets tried shots, different medications, etc and nothing worked. He was constantly scratching to the point of infection. Then our dermatologist vet suggested we try the Royal Canin Hypoallergenic Hydrolyzed Protein Cat Food. This meant having all our cats on this food, so we were a bit skeptical about all of them liking the change. They actually all love this food, their coats are shinier and less matted, and it seems that it cleared up our long hair cat's allergy and scratching issues. We have only been using it for a little over a month, but so far so good! SO, we are satisfied with this cat food and will continue using it! July 6, 2014
Rated 5 out of 5 by Fast and easy and it is working on his allergies After a year of allergies and feline MSRA from licking himself constantly, the only thing that worked for my poor cat was prednisone which is not good to give as we all know. My excellent vet said we should try the hypoallergenic royal canin and I was skeptical because the allergy was seasonal it seemed. Well he has been taken off all treats and food except this ( and what he catches unfortunately ) and he is doing amazingly well. I reduced his prednisone to every third day now and he is doing great. It is my understanding now that many cats are allergic to chicken and turkey so maybe that made his allergies to other things like grass heightened. The price while seemed high, actually isn't because that is all he eats and the bag is huge and will probably last 6 months. Quick delivery to my door ! June 25, 2015
Rated 5 out of 5 by Kitty loves this food) Kitty has skin issues,,,,,,changed to this food,so far so good,,,,,,,,praying that it continues to help w skin problems, thanks) March 4, 2015
Rated 5 out of 5 by Well worth the price. My cat is healthy again! For the first 9 months of his life, my kitten was plagued with numerous health issues: stomach problems, vomiting, explosive diarrhea, and lethargy. After trying over 6 types of top of the line food, my Vet suggested Royal Canin RX diet. The high price hurt at first, BUT, within a month, my kitten perked up and his symptoms slowly subsided. He is now healthy, happy and back to making up for lost time! Thanks Royal Canin and Chewy February 23, 2015
