What interesting things has your cat destroyed

My family's cat selected a cross board on the picknick table as her scratching post. There was no deterring her, she decided that that was the best place to sharpen her claws and did so very, very frequently. She was quite the little hunter so of course she had to keep her claws in tip top sharp condition. She pretty much wore right through that board after a while and my dad had to replace it. She didn't like the new one, thank goodness, I guess because it wasn't aged or something. She moved on to a rail post on the deck, same story with that board.
