There are low phosphorus commercial cat foods specially formulated for cats with kidney issues. Many kidney care diets require a veterinarian’s prescription, but some don’t.
These reviews will help you find the best cat food for kidney health for your cat. We’ll talk about both prescription and non-prescription options, so be sure to always follow your vet’s exact instructions when choosing cat food.
