Ever watch a cat play with it's prey? That's what I want to see today.
Pin them down, let them get away once or twice to give them a sense of hope. After a couple of repetitions of this, the prey knows how it's going to end, and they give up.
Maybe it's a bit cruel, but it's part of a cat's nature, and can no more be changed than the inevitability of today giving way to tomorrow.
