Technically it’s an obligate carnivore that must eat meat. All cats are obligate carnivores. OTOH, some carnivores, like wolves and other canids, could survive on a vegetarian diet, but they don’t in the wild.

To get even further into the weeds, almost all herbivores will opportunistically eat other animals; I think most people have now seen videos of horses pursuing chicks in a barnyard and hoovering them up.
