Grass snakes prey mainly on amphibians, especially the common toad and the common frog, although they may also occasionally eat ants and larvae. Captive snakes have been observed taking earthworms offered by hand, but dead prey items are never taken.
Corn snakes usually consume rodents, but you may get an occasional snake that prefers lizards. A baby anole or Cuban anole might entice a reluctant snake to eat. However, wild lizards often carry parasites, so this might introduce parasites to your snake. Parasites can be handled by your herp vet, should this occur.
