BP Weird Behavior

I have a ball python that does this too. He is just weird. I would catch him rubbing his face on his wood log maybe once or twice a week— I moved him into a rack and don’t see him all the time now like with a tank, but I’m sure he still does it. I think maybe he likes the sensation or something.

One other thing: I've noticed many snakes do this (instinctively?) after they eat...I assume they are wiping the prey scent off their face, since meeting
up with another snake and smelling like prey might be detrimental to their survival, ya?
