Their tank must be kept warm or they don't eat because snakes don't eat when they get cold. In the wild they eat fish, frogs, or small mammals and in the classroom they eat mice. Hawks, eagles, and bigger snakes eat them. The corn snake lives alone. It lives 15 to 20 years.
Breeding requires a cool winter dormancy.
It takes 4 to 6 weeks and 2 months before hatching starts. They can lay up to 4 to 12 eggs. After they hatch they stay in their shell for several days before leaving it. Certain tree trunks are too big around for the concerting type of locomotion to be applied. However, the North American corn snake has no difficulty in climbing such trees.
