I have noticed something similar, but also pretty odd. My BP seems to love everyone who has held him. I would just hold him on my arm and he would slither on to the next person. Except for one. My friend Colt. The only thing that is remotely different about Colt is the fact he is a vegetarian. So I wonder if that may have some sort of difference. I know that eating only vegetables will actually change your scent. I mean my snake actually started to go towards him, then just stopped and changed course suddenly. It was pretty funny.
