Cater to the precise needs of your cat with the Royal Canin Veterinary Diet Hydrolyzed Protein HP Dry Cat Food. Formulated for use as a short-term elimination feeding and as long-term nutrition for cats with food sensitivities, this recipe is made with hydrolyzed soy protein, which helps to support digestive and skin health. It’s also enriched with nutrients to support the skin’s natural barrier and digestive flora, and as part of the Urinary S/O Index, it promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals. Based on 40 years of science and observation, Royal Canin supports the health of your cat by providing him with precise nutrition and a true understanding of his specific needs.

Key Benefits

  • Hydrolyzed soy protein, composed of low molecular weight peptides, is highly digestible and supports gastrointestinal and dermatological health.
  • Optimal amounts of B vitamins and amino acids help maintain the skin’s natural barrier effect.
  • EPA and DHA acids are long-chain omega-3 fatty acids that promote a healthy skin and coat.
  • Specific nutrient blend helps to regulate intestinal transit and helps support the digestive flora.
  • Part of the Urinary S/P Index to promote a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.

  • Great option for cat with urate bladder stones

    By on

    I was taking my cat to the vet every few weeks with bladder stones, even though he was on a urinary prescription diet. Finally, I had the vet send a stone in for analysis, and we discovered that my cat had urate stones, which are very rare in cats, and therefore there is not a prescription diet made specifically for these types of stones. Lucky me. After discussing with some colleagues, my vet recommended I try feeding my cat Royal Canin HP. Since I began feeding this food along with a high quality wet food, my kitty has had significantly fewer trips to the vet for bladder stones. If your cat has not responded to other urinary diets, ask your vet about Royal Canin HP.

  • Hydrolyzed Protien dry cat food has stopped my cats barbering.

    By on

    My neutered, 6 year old cat was barbering himself badly. He had been eating Science Hairball light. I have now switched him to Royal Canin Hydolyzed protein dry cat food. He also gets Royal Canin ultra lite wet every day. He is calmer and he is not pulling his fur out. My vet recommended the new Royal Canin Ultamino dry food because he does have a lot of allergies. We will try that when he finishes the first bag. I am so impressed with his behavior with the Hydrolyzed protien. I feel we have found the solution using either dry food. Its very easy when you order from Chewy and you get it fast.

  • Thank you Royal Canin

    By on

    My cat has IBD and before he always vomited for every one or two weeks. That was nightmare in my life. I brought him to see different vets for this problem. Finally, a vet recommended this food to me. Even though the price is more expensive than a regular cat food, I still want to give a try. After my cat changes to this food, no more vomiting and he also gained a lot of weights! Thanks Royal Canin for giving my cat a brand new life!

  • My Royal Canin Dry Food Discontinued-

    By on

    I first ordered Hills Prescription Diet, Skin/Food Sensitivities because it sounded like it was the closest dry food to what my cat ate before. (Royal Canin Venison) But it didn't work out, Lily wouldn't eat it. So bad choice I guess. I decided to try another Royal Canin dry food to she if my cat would like it better and to my surprise, she's okay with it. Not as crazy with it as with the Venison, but she's eating it so I guess that's what we'll stay with since the other has been discontinued.

  • Great Customer Service

    By on

    We had not ordered this particular item before and Chewy still had an old address (we had just moved in the last few days). When I called because of the misunderstanding, the service representative immediately updated our information and called our vet to verify the prescription diet. She called me back in a matter of minutes and let me know that the item would be shipped by end of was and I appreciate their prompt attention to this matter. Bogey thanks you big time........he loves his new food!

  • My cat has IBS.

    By on

    My cat use to puke every three days. Our old Vet didn't have a clue what was wrong with her. When we moved and found our current Vet, they took the time to help figure out what was wrong with her. They put her on some meds, but introduced us to this food. Now she's off the meds, and had been on this food for over a month, and she's only puked once because my kids fed her some treats that I had put away and apparently does not agree with her IBS. We're thankful for this food! Plus our cat really likes it! =)

  • Cat with major allergies

    By on

    My cat Monster has had allergies and we have tried so many different things to figure it out. He will scratch his face and ears until they are bleeding. My vet recommended the Royal Canin Vet Diet and first he was on a different bag in purple and after 8 weeks we had to step up to this hydrolyzed HP. Monster loves the food, eats it up and so far so good, no itching or bleeding! My other cat who by default has to be on the same food also loves it.

  • Chewy - Best Place for Perscription Foods

    By on

    My veterinarian prescribed this food for one of my cats. I ordered it from Chewy and sent them the prescription. They shipped it immediately. Does it get any easier and convenient than that? I like doing business with Chewy. My cat is gradually learning to like this food. He is elderly and has always had his brand so it is a slow process. It will be worth the effort if it helps with his inflamed bowel disease as my DVM thinks it will.

  • Our cats love it!

    By on

    After trying multiple brands of prescription cat food for our 3 kitties who have sensitive stomachs (one with asthma and various allergies), all of which got rejected, this food was a life saver! All 3 of our cats love the taste and we find them sitting by the bowls meowing for their mealtime now. The food sits well in their stomachs and we have never had a problem with it. I don't ever see us needing to switch foods again!

    Short of waiting for approval from our local vet. on the Royal Canin Hydrolyzed Protein Dry cat foo. The service and the price was wonderful! We were notified when the RX food approved and that the food was being shipped all on the same day. That was on Saturday, by Tuesday afternoon the package on at our door. Short of buying and picking it up at the Vets, you couldn't ask for better service. Well Done ALL of You.
