In the world of Tokyo Ghoul, probably not. Humans and ghouls are the only species that produce RC cells, which is why ghouls can't eat animals.

In real life, there are tiger salamanders. When their populations are large, some of their tadpoles spontaneously transform into cannibals that eat their own kind. They grow a larger body and bigger mouth.
