  • I'm torn on this

    By on

    My cat had to eat this food according to the vet, and there are very limited options for this type of food. However, the general quality of the food isn't up to par with what my cats eat now, and the one who supposedly had to eat this food for his stomach has actually been doing much better on regular food that's of a higher ingredient quality. I'm torn on what to say to other people though, because if you have a cat with digestion issues it can be nerve-wracking trying different things to see if kitty can keep them down. If possible I would recommend trying something else.

  • Good Price

    By on

    We have to buy this food due to our cat’s allergies. Bottom line, she likes it and it works. This stuff is very expensive anywhere you buy it, but chewy’s price is the lowest I have found. The auto ship option is also very convenient, as the nearest pet store that carries this (since a prescription is needed) is quite a distance from where we live.

  • It seems to work!

    By on

    After trying many dried foods for my poor allergic cat, and getting sent to a specialist for treatment, this food seems to be doing the job. Dippity the cat is no longer scratching herself ALL the time, and is apparently on the mend. Thank you to Royal Canin for making this food. Just wish is were a bit less expensive, but it's less expensive through Chewy than anywhere else I can find!

  • No more food allergies

    By on

    My cat was constantly pulling her fur out and throwing up her food, and she'd lost weight over the past two years. Since she's started on the Hydrolyzed Protein food she has stopped throwing up her food, and stopped pulling out her fur. She's a lot more energetic and playful now.The food has definitely made a difference.

  • My Cat Likes It!

    By on

    Had to put my cat on this food because she was having allergic reaction to something and itching a lot. So far so good. Just started her on it so not sure it's going to solve her problem yet. She likes the food which is most important to her. It's a prescription food so our vet had to OK the purchase first but all of that was done via email to the vet and I had the food in 2 or 3 days from the time I ordered it. Chewy.com price was the best I could find on the sites I checked. Some didn't even carry the prescription version of the food.

  • Brand new food, too soon to review

    By on

    I just started using this new cat food so it is too soon to tell. I will say my cat liked it immediately which is most unusual for this kitty and most kitties I've had. I'm still giving her wet cat food during the transition period. I'll know more in a few weeks.

  • Dr prescription does wonders

    By on

    My kitty was not digesting regular food properly. The vet recommended hydrolyzed protein and it has made a world of difference! I thought the second kitty would not want it, but she's fine with it and they are both doing very nicely now.

  • Cats love it!

    By on

    One of my three cats has trouble digesting regular cat food and the vet prescribed this hydrolyzed protein for him. He loves it and so do the other two! He only throws up once in a while now, not everyday, every time he ate, as before. I’m a believer.

  • Goggle this...is soy good for my cat? all i see is no it is not.

    By on

    I wonder why vets sell dry food with soy as #3 ingredient? Ive done lots of research on soy. I recommend you check out soy as an antinutrient. Ive been on high soy in my life so have first hand experience for sure.

  • Could not be happier

    By on

    My cat was sick from the day we adopted her with loose stools and took us almost 6 months trying -grain free, sensitive stomach foods, home made food, all the while going back and fourth to the Vet to figure out she could not process certain proteins. As a last resort before spending hundreds on tests, our Vet prescribed Royal Canin HP and in 3 days she was fine. Love this food for helping my baby feel better.
