 While obligate carnivores might be able to ingest small amounts of plant matter, they lack the necessary physiology required to fully digest it.In fact, some obligate carnivorous mammals will only ingest vegetation to use as an emetic, to self-induce vomiting of the vegetation along with the other food it had ingested that upset its stomach.Obligate carnivores include the axolotl, which consumes mainly worms and larvae in its environment, but if necessary will consume algae, as well as all felids (including the domestic cat) which require a diet of primarily animal flesh and organs.
