Maybe I am just unclear on what spinning itself is. Is it the snake wildly flipping about when it tries to move? Or is this referring to the "spinning" motion that the head makes when it is wobbling? Like, if you made a fist out in front of you, and started moving it in circles while keeping your wrist stiff..?
If spinning is just another term for wobble-head, then I will rethink my words. But if spinning is something dramatic where the snake has trouble moving, I will disagree with Nate, because my spider has never exhibited anything more than a slight wobbly head during feeding times.
