The Short Answer

It could be like a cat's. When you scratch a cat on the lower stomach and their hind legs go crazy scratching you, they don't do it on purpose. They actually do it to themselves sometimes. It's triggered because in the wild, when they would get pinned by the animal they're fighting, their hind legs would attack the vulnerable stomach of the other animal that is on top of them.
