My cat Chester loves to steal my plastic dixie cups from the bathroom. I started having to keep them in the medicine cabinet so he wouldn't do it everyday but sometimes I forget and I leave the cabinet open a little. The next thing you know, Chester is standing on his hind legs on top of the sink, nudging the cabinet open as far as he needs. Then, he grabs the cup in his mouth, jumps down and starts batting it around the floor. This amuses him far more than store bought toys!

Another funny thing that Chester does is he loves those springy doorstops that are attached to the wall near the baseboards. For a while, he had a habit of "strumming" the doorstop in our bedroom until we woke up in the morning. He would strum a few times (making quite a racket!) and then look up to see if we had woken yet. If we were not sufficiently awake (enough to feed him that is), he would go back and do it some more. We finally had to unscrew it from the wall in order to get some sleep on the weekends!
