That setup looks awesome!

The only problem is that, from what I've read on the forums, is that ball pythons are not arboreal, meaning they don't climb in trees (or really any climbing in general). Their bodies simply aren't built to climb. Building a structure for your python to climb on could result in an escape or a pretty bad fall . From what I've read, I ball python that is trying to climb indicates that your temps are off (looking for a warmer/cooler place).

Anyway, anybody feel free to chime in here, as I'm pretty new myself. But I just wanted to let you know what I've read before you build a complicated exhibit like that and do all that work.
