My son has a one year old ball python, we got almost two months ago. Snake is great eats f/t no problem, he is about 563 grams before last feeding. Never strikes or hisses, easy to handle ect... The only thing is he loves to constrict around my sons neck, my son is six. He never handles his ball python without me there so I'm not worried about safety just curious why the snake does this. The snake isn't simply cruising around he digs in and I have to unwrap him. I'm guessing its a security thing for the snake but I'm new to this. Any thoughts.
