I don't have a cat . . .

Avoid foods with grains in them; cats can't digest them. Meats, vice meat by products, serve them best. Some producers add vegetables and fruits, which cats may/may not like the taste of, but don't contribute to the cat's overall health.

Ideally, a raw food diet, just as they catch in the wild, is best. But if you don't like trapping/raising mice, squirrels, rabbits, voles, garter snakes, etc., best to stick with the cat foods.

Sorry, poor information not supported by a majority of the evidence out there.
