No I'm not sure about that, which is why I have to ask the question. One of my snakes sold to me as a male is doing a lot of tail wagging and scent marking when placed with another snake sold to me as a female. This is my first time trying to breed BPs, so I need to get these behaviors straight. And I guess I need to find someone who knows what the #@!! they are doing to sex these two. At least I have one pair that has figured it out! Another question... Will two females that are "in the mood" try to court each other?
