My first ball used to use its tail as a decoy. The first time I saw it I thought I just imagined things, but then I saw him do it several times after that.
He would slowly move the tip of his tail back and forth. It would usually get the mouse's attention, and just kind of hypnotize it. As the mouse would watch the tail mesmorized, the snake would come up from behind and blind side it.
It was pretty cool...
