I worked in a pet shop for a few years and every day I was bitten by a hamster, gerbil or mouse, and they hurt. BPs are generally friendly mine has never bitten or hissed. I kiss my snake on the nose, it doesn't bother it. It doesn't like having its head held and sometimes jumps when you brush against its head if you come from behind, but as long as you don't hurt it, it shouldn't bite.
