They don't grow to be very big, are incredibly mild mannered snakes and get along great with almost everyone. Keep them in a 20-gallon structure, even as adults, with temperatures in the 70s and 80s. They can live alone or with another corn snake. They only take a few weeks to warm up to their new owners. As soon as they become comfortable with you, they have no problem being handled and are quite calm and fun to be with.
Kingsnakes like to eat.
In fact, they'll eat just about any creature you put in front of them, so house Kingsnakes in individual structures. Keep them in a 20-30 gallon structure at temperatures ranging from the 70s to the 80s. The adults can be quite large, but are also quite fun. There are many cheap ball pythons on the market that were caught wild or hatched from wild eggs. These ball pythons can be dangerous for the inexperienced snake owner.
