Helps reduce skin and GI reactions that may be a result of sensitivities to common proteins found in pet foods

Helps minimize risk of reaction with proteins that are broken down to a size that’s less likely to be recognized by the immune system

Reinforces the skin barrier with essential nutrients to support healthy skin in cats with skin sensitivity and irritation

Helps support healthy digestion with an exclusive blend of fibers and prebiotics

Whether a veterinarian has determined through an elimination diet trial that your cat has food sensitivities or that she requires long-term support for her skin and GI issues, your vet recommended Royal Canin Hydrolyzed Protein Adult HP for a reason. This highly palatable diet is designed for adult cats. It’s formulated with hydrolyzed soy proteins, composed of low molecular weight peptides, so they can be absorbed in the digestive tract with a reduced risk of triggering an immune reaction. Optimal amounts of B vitamins and amino acids reinforce your cat’s skin barrier. Omega-3 fatty acids EPA and DHA help promote healthy skin and coat. An exclusive blend of fibers helps support healthy digestion in cats prone to digestive upsets, including diarrhea. And with strict manufacturing procedures to help avoid cross contamination, you can confidently feed Royal Canin Hydrolyzed Protein Adult HP long-term to cats with food sensitivities.

Solved Diarrhea Issue

This is the only food that my cat can digest and does not lead to diarrhea. I wish there was a wet food option for cats as well.

Healthy cat

The cat for which I was buying this hypoallergenic dry cat food lived 20 years.

Caused so many problems rather than fixing them

Caused my cat to need emergency cystotomy surgery to remove crystals the size a human would have. Was told by Royal Canin that "there's no guarantee the SO Index will prevent crystals". That answer is entirely unacceptable and says it all about the company.

Saved my kitty

I adopted a cat full of open sores that the vet couldn’t fix. She was on antibiotics and creams. Turns out she was allergic to regular cat food and scratching open her skin. This food changed her life! She’s no longer in pain, she’s living happy and healthy. Just wish it was a little less expensive!

Protein rash is back!

My cat is allergic to protein. She ate this for year's. The last three bags has left her with rashes. I asked the vet if they switched the formula. I was told no. Today, I'm researching renal food for my other girl. So, I decided to research Sunami's food, read all this crap and oh my goodness....we were about to book her in to the vets for blood work, as we could not figure out the rash problem. The rash is only present when she gets protein in her system. I emailed RC months ago regarding their negligence- they left my city and surrounding towns dry of this food. RC did not respond. Typical. Reading all this just infuriates me. All these formula changes RC does. I think I'm better off to check out Hills or even Purinas Vet line.

Please go back to original formula.

My cat used to love this food, but ever since we opened the most recent bags after noticing the change of the bag and then noticed she has done a complete 180. Instead of running over to her bowl and eating her food, she now avoids it until she is hungry. We attempted adding warm water and she licks all the water off. I suspect it's due to the formulation change everyone else is mentioning. Something definitely changed, which is a shame given how limited the options already are for HP cat food. Like other cats, her issues with vomitting and her stool which had gotten better on this food is now worse. We will have to find something else.

Formula Change

We went through several RX foods and this one is the only one our cat could tolerate. Opened new bag and she will not eat it unless she is starving. Even then, she only eats a tiny bit. Very disappointing.

Formula change resulting in vomiting again

My boy has been working with the vet for the right mix of prescription food, food he could tolerate and food he liked to eat. Finally got the right combination then Royal Canin HP was out of stock most places and upon it's return, the formula had to have changed. I first noticed when scooping into the dish. The kibble seemed different - lighter? Less than 2 days after opening new bag, my boy started vomiting again daily. What changed and why, Royal Canin? Rating would be higher if formula wasn't changed for the worse.
