Ok, I'm going to pick up a colubrid as a pet for my son. Of course I'll be taking care of it but I want something that he can easily handle without worry. He's going on 7 years old and he loves my snakes but he is still uneasy about handling anything bigger than a young ball python.

I know nothing about colubrids as pets. I've only ever had constrictors. I'd like opinions on temperament, ease of care (no extra heat or special housing requirements needed), ease of feeding (no special diets), doesn't get huge (no black rat snakes) etc..

I'm thinking corn snake but I'd like your take on your experience with different species.

Thanks!
