We have had ball pythons in our house before and we knew the gender of them because the people at the store checked for us. But all of them have long past (aka: our first girl accidently fried herself. ;_; My sister's baby bp couldn't -cough- poop. And the other one we had wasn't nice and bit my dad. xP My dad has had snakes in the past and had never had an adult bite him). But the one we have right now(we've had him for about.. a year? I dunno.) we don't know what gender it is because we bought him from a petstore. His name is Mr. Sister and we don't plan on changing it lol. Could I possibly get some information on how to check if its a girl or boy?
