What interesting things has your cat destroyed

Outdoor cats don't destroy things so much...but...I am not making this up: One year two young cats living with me found a picture book called "The Haunted Birdhouse" (it was haunted by a bat) in the shed, and they pawed through the book several times, not tearing it, but paw-printing it. Another year, one of those cats' granddaughter found a book by Dave Barry--I don't think it was even one that contained an anti-cat joke--and clawed the covers. Repeatedly. Of course, either or both of their selections *could* have been a coincidence. I guess. Maybe.
