Thank you, I was just about to ask the same thing as Steve, as a King may be in my future.

I've been warned about their venom; how serious is it, in your experience?

Are they climbers? I give most of my new world rat snakes branches and hammocks, and they use the heck out of them.

As for burrowing, do you give them a thick substrate for this? I give my rubber boa a pretty deep pile of aspen for her burrowing pleasure (err, that sounded dirty, didn't it?), and she really seems to like that.

Finally, do you use very large enclosures? I like to give snakes plenty of room and furniture so I can watch them doing interesting things, but not all of them are comfortable with big spaces. Are these guys active enough to utilize the space?

Thanks
