Low protein diets for cats
Cats are obligate carnivores, they can not manufacture certain amino acids. If feeding a diet, then use a premium diet that has as its protein source some animal product.
Plant proteins are not easily digestible and can cause a fair amount of wear and tear on the kidneys. If your kitty suffers from liver disease or kidney disease, then use a prescription diet such as Hill's/Iams/Purina/etc. Prescription diets come in wet and dry preparations.
If you are cooking for your pet, than make certain that animal protein is a key ingredient. I would consider anything less than 18% as low protein, other sources will have moderately different levels according to methods used to measure protein percentage, whether on a dry or wet basis, etc.
