I figure the best way to respond to everyone at once.
This would be a cage for a young to juvenile carpet? I guess building a 4 ft x 2 Ft x 4 ft version once the snake was older. I also agree that this would be great for a boa eventually. Ruby my BCI would be great in this enclosure but even she is a little large for this cage. Perhaps once the carpet is grown I would put a tree python in this enclosure or a BRB. If I get another BRB it will be an adult female. I put Ruby in the enclosure for a few minuets and she explored it and seamed to enjoy the climbing space and the dark shelf on top. She just needs more floor space like an adult carpet. It was difficult to get her out of it. LOL. I plan on building a few "enrichment" enclosures for my more active and aboral species over the next few weeks and soon start construction on a huge retic enclosure for Rainbow and Aurora.
Thanks everyone for the feedback.
As for design.... do you think it is to tall? Would they run the risks of falling? Is the heat being mounted on top ok as long as ambient temps are good and having the hot spot on top?
