What interesting things has your cat destroyed

I think sometimes cats enjoy certain sounds, like my girl has an affinity to the noise of her claws on drywall. (Ugh) She also likes to hear the flapper thingie on the air conditioner clacking away. She will climb the bookshelf and stand on top of it just to bat at that flapper so she can hear it clack. She'll look at me while doing it and I swear that cat will be smiling. So, perhaps your cat likes the sound of glass shattering and has no idea why you don't enjoy it too. In my kitty's case, she destroyed one corner of an automan in our living room and then when the stuffing came out she didn't like the feel of it on her paws anymore. I finally got tired of seeing it that way, so I patched it with a (sort of) matching piece of cloth. She is now in the process of destroying that, so I can't win. When I give her a toy, she will look it all over, appreciate it with her eyes and nose, and then she will proceed to make it 'her own' by biting little holes into it or by breaking it in some little way. She did that with an old tote bag that she seemed to like, so I gave it to her. She understood that it was hers and immediately made little tooth marks in every corner of the bag. Once that was done, she never damaged it again. It was like, "there. I signed my name. Now it's mine." I gave her a scratching post/cat toy combo recently, and the first thing she did was rip one of the two fluffy toy balls from its elastic cord at the top of the post. It was much more fun to play with as a rolling ball rather than a swinging one, thank you very much. A few days later, she had the other fluffy ball ripped off as well, so I just removed the elastic cords from the toy altogether and now she's quite happy with it. Apparently those silly dangling balls just got in her way when she wanted to scratch at the post, so she 'fixed' it.
