My young cornsnake has started dancing a lot. He gets up against the glass, lifts as much as he can up in the air, and sways back and forth. It's not a steady motion, he wiggles around and will eventually get to much of his body in the air and lose his balance. He's usually prety active and seems to be healthy, I'm just wondering if anyone has seen behavior like this. Also, I call him "he", but I don't know what ses he she it is.
