I work for the Humane Society and we got a BP in last saturday and I'm adopting it since I've always wanted one. Is there anyway to tell how old BP's are? How many mice should i feed to him every week? I thawed out a frozen mouse monday night and he seemed to enjoy it but I'm not sure if one is enough for him. He's about 3 feet long. This is going to be my first BP and I'm very excited about finally owning one. I'm looking forward to learning more about them and getting to know everyone here as well.
