What do Common Garter Snakes eat?

a common garter snake feeds on small rabbits, mice, gophers, and squirrels, birds, leeches, lizards, pinkies (baby mice), small frogs. Small garters eat small minnows, but not too big as they cant digest it.

Crickets are bad for them, as they can't digest the shell. Earthworms have no nutritional value for them.

Food is swallowed whole. Garter snakes often adapt to eating whatever they can find, and whenever. Although they feed mostly upon live animals, they will sometimes eat eggs as well.
