My cat does crack.
She has this wire toy that she likes to play with.
If you won't play with her, she'll do it herself. She holds the wire down with one of her back feet, then she starts turning. The wire, of course, starts to turn, so she chases it until she gets dizzy.
She does this all the time.
No, really, I'm not kidding.
