The ads for
kitten food are correct: kittens do have different dietary needs than adult cats. Specifically, a kitten needs one and a half times the protein required by a mature cat. And cats in general have high protein requirements. Proportionate to their body weight, cats require three or four times the amount of protein that humans require. (Humans are omnivores and take in a large amount of plant food, but cats, are almost exclusively carnivores.)
