So, a distant relative of mine has had a BP for about a year, and he no longer wants it because he realizes that he's not taking care of it adequately. His mom, knowing that I already own a snake (a corn snake) got a hold of me and asked if I would want it. I have yet to reply, but I'm going to say yes.

What should I see when I pick this guy up? He's a year old, so how big is he going to be? What size mice should I feed him?

Any advice is greatly appreciated, I'm going to look up some care sheets after I post this. I'm a long time corn snake owner, but I have no experiences with BPs.
