My cat's favorite toy of the moment has a fuzz ball attached to a metal spring that is protruding from a small block of wood covered with carpet. She runs far away and then pounces on it when she thinks it's not looking.
I have recently seen a toy that is basically a big plastic circle with openings on the top and a ball inside, so that cats can stick their paws inside and bat around at the ball. It seems interesting, but I'm wondering whether cats would get bored with not being able to get the ball out.
Anyway, I'm curious about what kinds of toys you buy for your cats, besides the usual toy mice, balls and things with string on them. Do they enjoy a particular toy, and if so, which one?
