There are no vegetarian snakes. Some merely eat worms or insects, but none survive without meat.
Don’t be discouraged; you can still own a snake without having to handle live food.
It’s strongly encouraged by many snake experts that you train your snake to eat dead mice or small rats instead of live ones, anyway.
This is primarily because countless snake injuries and even deaths have been caused by live food being introduced into a snake cage, scared mice can do a lot of damage with tiny, puncturing teeth.
