Helping cats and dogs live their healthiest lives.

Helps stimulate appetite in cats and encourage eating with aromatic kibble

Helps reduce the risk of skin and GI reactions with proteins that are broken down to a size that’s less likely to be recognized by the immune system

Helps compensate for decreased appetite with a highly palatable energy-dense formula to reduce meal volume

Helps promote kidney function with a precise antioxidant complex, fatty acids from fish oil, low phosphorous, and target protein levels

Your vet recommended Royal Canin Renal Support + Hydrolyzed Protein for a reason. This highly palatable dry cat food is specially formulated to care for the kidney health of adult cats under veterinary supervision. The aromatic dry kibble stimulates your cat’s appetite and encourages eating. Hydrolyzed proteins, composed of low-molecular-weight peptides, minimize the risk of a reaction due to a food sensitivity while also helping support kidney health. And the energy-dense diets provide nutritional support in smaller portions, since cats with kidney challenges have decreased appetites. Plus, they contain a precise antioxidant complex, fatty acids from fish oil, low phosphorous, and targeted protein levels to help support kidney function.

My Cat Loves the taste and feels better!

Our 12yr old cat has kidney disease and irritable bowl syndrome. For years we have been searching for a food that she could digest or work for her IBS. FINALLY after taking our cat to a new vet this was recommended. A complete life saver and she loves it! Her IBS has cleared up no more diarrhea and her energy has returned! She is even gaining her weight back. I am so glad for this food..

Great product for senior diabetic cat

Our 16 yr old Patches was recently diagnosed with manageable diabetes but had food allergies. Her skin was scabby and she was miserable. The vet pulled out your product guide and we found this which has greatly improved her coat and weight back to normal.

This food came highly recommended by my vet for my cat with kidney and heart problems. I would like to give it 5 stars but I often have a difficult time finding it. It is also a bit pricey. The cat who needs this food has 6 siblings who love it and he is willing to share with them. My cats are older and several are on Royal Canin food.

Best taste

I tried this and it was the only dry kidney food that my cats would eat on a regular basis. They also liked the Canned food E.
