Tack on another addition to the cat tree files, as we bring you The Climber. First spied on Modern Cat, this super classy climbing extravaganza is so out of the way, it's practically out the door! The unique design allows you to attach to any door so your kitty can climb and scratch to her heart's content. Since it's made of durable sisal, your cat's preferred scratching post will be this, and not your new couch. What's more, the brand spankin' new designer, Cat Livin, lets you customize your order so it will match your already stylish decor! Free shipping on orders over $20 only adds to the appeal. Now if only I had a cat . . .
