My senior cat likes Hills 7+. Is it good for his kidney diet?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 17 years and 8 months old | 9.5 lbs

Hi I was speaking with one of your vets before about senior diet cat foods that are less stressful on the kidneys. Suggestions were purina pro plan 11+, hills science 11+ & royal canin aging 12+, all canned. He wasn't crazy about these but seems to like hills science diet mature 7+ savory chicken minced canned entree. It says its also lower in phosphorus but would love someone's opinion or experience with this food. Thx!!

Hello, & thank you using Petco Pet Education Center, formerly Petcoach. The most important thing for you to consider is the palatability of food for Tony. The best food for the kidneys will do him no good if he will not eat it. That being said, I think the Sci. Diet Adult 7+ is an excellent choice. The phosphorous level is actually a bit lower or about the same than in some of the Royal Canin renal diets. He should do quite well on this. Take care.

    Unless Tony has had labwork to show decreased kidney function, he doesn't need to be on a diet with restricted phosphorus levels. The most important thing is that he does eat, and if he has renal disease ensuring adequate nutrition is very important. I would talk to your vet about what types of diets they recommend, but for me it is much better for a cat to eat a diet they like rather that not eat the diet they're supposed to. Phosphorus binders are always an option as well, and generally I recommend wet foods compared to dry for the increased moisture content. I hope that helps, good luck!
