I brought home a new toy for Lucy one evening and it was a hit. It has a furry mouse that spins around in circles when she bats it. I could hear her in the living room from upstairs and the noises got progressively louder. Finally I had to see what she was doing and when I peeked down in the living room she was lifting up the whole thing with her mouth or paw then letting it drop on the floor, where it would rattle. Finally she somehow managed to flip the whole thing over and I just left it so she didn't make a lot of racket during the night.
