There are two main brands of veterinary specific diets which support diseases in dogs and cats, these are Hills and Royal Canin.
For chronic kidney disease, these foods are called Hills K/D and Royal Canin Renal diets. Both are essentially the same in terms of how they support your cat through kidney disease. Most importantly, the food helps by protecting the kidneys from further damage with lower amounts of phosphorus and salt. They also support your cat’s natural ability to build lean muscle with a high level of essential amino acids.
Now I’m going to show you the difference between the brands of kidney food available and the flavours. I would offer to try the foods myself but I’m not stupid so, instead, I’m going to use Milo as the taste tester!
