Diet is the brick and mortar of health. This web page lays out some often-ignored principles of feline nutrition and explains why cats have a better chance at optimal health if they are fed canned food (or a balanced homemade diet) instead of dry kibble.
Putting a little thought into what you feed your cat(s) can pay big dividends over their lifetime and very possibly help them avoid serious, painful, and costly illnesses. An increasing number of nutrition-savvy veterinarians, including board-certified veterinary internists, are now strongly recommending the feeding of canned food instead of dry kibble.

1) water content is too low
2) carbohydrate load is too high
3) type of protein – too high in plant-based versus animal-based proteins
