Here are a couple pics of the custom cage I am building for a pair of BP's. It measures 40"x33"x15" (lxwxh).
This is from a top view, you probably can't see it but there is plexi on top. The entire top comes off so I can get inside of the viv. We still need to get locks for it.
This is the front, instead of making vents I just made a full side of screen.
It is definately not done, but I am not getting the BP's until March so I have a while to finish it.
