I've said it before, I truly believe cats are evolving. It's been a slow process, but it's happening. Don't believe me? Watch this cat open doors. Yep, a closed door is no big deal for this cat. He just opens the door and prances right through. Even when his owner puts a tub of water in front of the door, this cat just makes a few adjustments, jumps around it, and OPENS THE DOOR.
