Here's a picture of my wooden enclosure, so you can see what I'm talking about... I love this tank, but can't afford to have them for every snake! I got it at a local vivarium, and they offered to buy it back (at about 40% cost) when I'm ready to upgrade to a 20gal.

Ignore the guard-kitty on top, LOL... it's the only good shot I have of the tank!
