My snake dangles herself quite often. Seems like she's an arboreal snake.. Kinda weird if you ask me. She'll wrap around my wrist once and dangle the rest of her body like she's waiting to snatch a bird out of the air.

But my python seems to be the exception to most rules about balls.
She has never refused a meal, eats during shed and all that good stuff.
I consider myself very lucky to have such a cool snake.
