There are a lot of cat toys on the market, but Henry will only play with the little soft mice that come three or five to a pack. They're only about two inches long, (four if you include the tail), and have white heads, pink ears, and various colored bodies. Henry LOVES these mice!
He goes wild if you hold one from the tail and dangle it anywhere him. We have to warn company not to pick up any of the mice if Henry is in the room because he'll leap up and grab it, accidentally taking part of their finger with it.
We've tried other toys, but he's usually frightened if the toy is too big or makes any type of noise. He does like to chase string, though. Cheap toy!
How about your kitty?
