When it comes to boas I would insist on confirmation that it is indeed a male since the females can be considerably larger. Our 16+ year old female BCI is almost 9 feet in length and certainly would not fit in some caging options that would be perfectly wonderful for a male her age. Boas are wonderful snakes btw the way and generally grow into beautiful adults if handled correctly as babies. Just mind their longer strike range and remember that most boas are aggressive feeders that enjoy their mealtime.
