Can a healthy cat eat Royal Canin renal food if they don't have kidney disease?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 17 years and 10 months old | 9.5 lbs

Hello tony does not have kidney disease and he is not in early stages of kidney disease (like my vet recently thought) but I had bought a royal canin renal Food kit and he loves the renal dry food and won’t eat any other dry food now. He is mainly on a canned hills rx senior diet but likes the renal dry as a snack or sometimes with his wet food. Is it ok for him to eat this renal food even though he doesn’t have kidney disease??? Thx!

Yes, it is ok to eat renal food, but only as a treat or supplement to the main diet of Hills Rx Senior. Renal food is lower in protein than normal cat food since the kidneys can't handle excess protein when they are failing. So it would be best for long-term health if Tony gets plenty of protein, which is in the senior diet!
