I just recieved my snow, and im not sure about a few things. 1. The pinkie I bought looks too big for the little snake. 2. Is there some way you can tell if it's a boy or a girl without visiting the vet? 3. If the answer is no to #2, then how much would it cost for a vet to sex your snake? 4. Im not sure how old it is, and I will post a pic asap, but right now i dont have one.
