Snakes are great! Though I have worked with snakes in the past, I just got my first snake this month... see the post in this forum called "snakes", mine is about 5 or 6 posts in.
Oh, yah, I bet he's diggin the cage... he'll only grow to about 3 ft, so that's a palace for him!
Just be sure that, while he's young, he has a few small hides, one on the warm side, and another on the cool. If he can't fit snugly inside or under something, he could get stressed. Young snakes especially need a lot of security. In the wild, they would hide all day.
