Rabbit's foot on the end of a long heavy string - you hold the string
and throw the rabbit's foot out for the cats to pounce on. Best get
several - the cats will eventually destroy them. Works best on a
slick floor. This is the only toy my cats will always play with.

I went looking for a rabbits foot today, but the place that sold them years ago
doesn't anymore. I'm gonna look on the net. Yup, all my old cats loved them.
Great idea.
