I really hope this is the right place to put this (it was between here or BP Husbandry but I'm assuming here since it's more general discussion instead of care). But, my cute lil girl has done this twice now while holding her. She wraps around my fingers, gets real cozy, and then uses one of my knuckles to like... nuzzle? She's applying pressure but not much, and just rubbing her chin on me really gently. She'll occassionaly rub her body against my fingers too but that's usually like a position change rather than the nuzzling thing. I highly doubt it's a sign of affection, she's a snake (but science has been wrong), so do any of your guys' pythons do this?
