I'd like to get a boa sometime in the future but I can't decide if I'd like to get a male or female. Sizewise I feel that adult males are a little smaller than what I am looking for, but at the same time, there are some monster females out there and that is not what I am looking for either. Ideally, I'd like a boa that is about 5 inches in girth, I'm not so worried about length. Are those monster females somewhat rare or pretty common? Is it a matter of how much you feed it? Maybe I should get a female of one of the smaller species? What do you think?
