Congrats on your first ATB! They are awesome snakes! Now, about your set-up.....are you going to be getting a full-grown adult or a baby? This makes a BIG difference in cage size of course. Babies will stress easily of given too big of a cage.

Also....a basking lamp is not the best way to heat an ATB......they do not bask in the wild.....they go down for heat and spend alot of their time on the floor of their enclosures. So, I use a human heating pad for all of mine(set on low most of the time)......also, how resistant will the cage be to the high humidity? Don't want mold or bacteria to bloom in there because of untreated wood you know.

Any more Q's just ask away!
