Cats! You buy them $300 of the world's finest scratching furniture (posts, tree houses, straight-up scratch condos) and all they want to do is play with that tissue box you have left over from your cold two months ago. And unlike the scratching posts, which are meant to be scratched and always lose to claws, these tissue boxes won't go down without a fight. You think getting three kittens to gang up one one box will help you win this? Think again, buddy! That box held the expensive lotion-enriched tissue, and if it's going down, you're going down with it.
