I just got my first Carpet python about a week ago. After letting him settle in, I got him out. He immediately coiled around my hand and hissed. He hisses if I try to disturb him from his new hand-perch. He won't strike, instead he just coils tighter and tighter around my hand.
He is incredibly strong for such a little worm of a snake. In fact, he cut off the circulation to the finger he has knotted his head and neck around. Is this normal behavior for a baby coastal? I'm having a very heard time trying to get him back in his bin. He seems quite content to sit here and try to crush it with all of his might. I'm typing this post with one hand. He looks like a little green tree python perched on a branch.

How should I coax him off of my hand? Is he stressed, or is this hatchling behavior?
