Read this thread about Animal Plastics cages, it might help answer your questions about them: http://ball-pythons.net/forums/showt...69#post1763769

I would recommend that you get a T8, they cost less and have more room. You can even put 2 BP's in 1 T8 when you use a divider.

I don't recommend using a zoo-med UTH with AP cages. AP cages are made from 1/2" PVC and I have found that they simply aren't up to the task.
