Canines, the "killing teeth" are proportionately larger in cats than dogs. Cats require three times as much protein in their diets as dogs, and kittens need four times as much. Dogs can get by on a vegan diet but cats can't synthesize key fatty acids on their own and need to get these essentials from other animals' bodies. All cats, from big to small, have the same maw, designed with a singular, protein-seeking purpose.
