The various mammals belonging to the order Carnivora are meat eaters, but most of them will eat fruits, vegetables and other plant matter. (And, oddly, pandas are classified as carnivores, yet they live almost exclusively on bamboo.) That is, carnivores are not exclusively meat eaters—except for cats, that is. All cats must have animal protein and fat to survive, and though house cats might munch on cooked rice at times, cats as a group are truly “meat-only” animals.
