What interesting things has your cat destroyed

Back when my grandmother was still alive, she has three cats of her own. They're always in the kitchen waiting for a handout but the good thing about it is that the place became mouse free so no matter how annoying they could get, we still let them hang around the place. Now these cats are not your mellow type ones. They tend to fight each other and would make a lot of noise from time to time, especially on the roof. I thought that's the only time they're going to be a nuisance but no, two of them started playing with the loose ends of my shawl that as just sitting on the sofa. I caught them red handed, scratching it and stretching on it until it's an ugly mess of runs and tears. They've also ruined my mom's wooden table by treating it as a scratching pole. Cats can be real swell but I think my grandmother's are the exception.
