My new BP has been doing something unexpected since I first got him. Every time I come near his vivarium, he slithers out to see me. At first I thought he might be associating me with food, but whenever I reach in to pick him up, he curls around my hand as if he wants me to take him out. I've kept snakes and never had them show any kind of affection. Could there be a reason for my BP coming up to me when I approach? Is this common?
