One of my boyfriends females BP's have exhibitted behaviors like that .... Mel is his snake and she makes sure that i know that. When I come into his bedroom she will get out of the blankets on his bed to curl up on his legs.... any other time of the day she will stay curled up in the blankets. lol.... I try to let her know when I am coming into the room and stay on the opposite side of him from her.....
