What is Low Protein Cat Food?

Cats, like other carnivores, need protein to stay healthy. But in some cases, the amount of protein in normal cat food is too high for your kitty. If your cat has liver or kidney problems, excess protein can put additional strain on their organs.

Luckily, a low protein cat food can help ease this. And even though this cat food contains less protein, it still contains all the nutrients your kitty needs to stay healthy.

Most low protein cat foods are really tasty in order to stimulate the appetites of cats with illnesses. And they come in both dry and wet food, catering to even the pickiest kitty.
