I know you can either sex or probe your bp to find the sex. I have 2 bps one from pets mart (supposedly a female) one from pet co (supposedly a male). I would like to sex them and find out for sure. They are about 2-3 months old. Are they too old to "pop" them? Should I try to probe them myself? I have watched many a snake been popped and probed. Or should I find a vet to probe them?
