I am purchasing a new enclosure for my BCI from Animal Plastics, and I am torn between two, those being the T20 (6'x2'x2') and the T25 (6'x30"x18"). The boa is about 2 years old (unsure on the exact age) and roughly 5 ft long, but she is definitely still growing. I want to give her a 6 ft cage minimum, but I am unsure if I should put extra height or depth. I have read that the 18 in height may be easier to control humidity in, and that depth is more important than height, but I feel a 24 in would allow more use for climbing, as 18 doesnt feel like much to me. I also feel this would be more convenient for me, as I already have another animal in a T10 (4x2x2) and using the T20 would make stacking a little more convenient (to avoid bowing or warping with a T25 I would have to put a few two by fours in between them) but I'm willing to forego convenience if more floor space and less height would be better for my boa. Just want other people's opinions on what I should do!
