Ball Pythons CAN bite, but rarely do. My old roomie was afraid of snakes, but was okay with me having a BP if I kept it in my room. Well, I walked around holding her until one day I was sitting next to my roomie on the couch and asked if she wanted to pet her. My roomie was nervous about that, but I said "Just touch her tail, here, I'll watch the end with teeth. She doesn't bite anyway, or never has before, but just so you feel better I'll watch her head so you can touch her." The roomie pet her then, and slowly but surely she got more comfortable until finally, when my girl got an RI, my roomie was so comfortable she even helped me hold her for shots.It's a process, but it's doable.
