Here's my opinion and it only just that-- my opinion

I have a few ball pythons and they are very different from my few boas. Different personality, different husbandry needs, different climbing needs.

I have my boas (all females) in RBI 2x3x1 cages heated with RHP's. My two yearling boas will go into their permanent enclosures in the next several months and I've chosen the AP A30. This measures 4x2x6. I believe that allowing boas the opportunity to climb (as they do in the wild) is a responsibility as their keeper. I also beleive that such height will allow them uber chances and choices for thermoregulation. There will be a few levels in the cage with shelves that have holes cut through them allowing the boa to climb and, well, be a boa.

I fully realize that there are many people who keep boas in smaller enclosures and their boas thrive and breed and eat. I also understand that male boas might not need such large enclosures (since they don't get as large as females) but I do believe that providing the largest enclosure one can for a large and 'outgoing' snake, such as a boa, ought to at least be considered.

Again, these are just my opinions-- and I'm sticking to them...for now
