Houdini Cat Encounters Water Trap

Sven has a cat named Muldar who is a genius. He wants what he wants and no one is going to stop him. Closing the door? Pfft! Muldar will just open it. Set a pan of water in front of the door? Not a problem. For Muldar. It's a problem for Sven. Sven noted that the water pan was added to keep Muldar from scratching at the door, and that putting a round knob on the door (as has been recently suggested) would make no difference. I concur; Muldar would just figure out how to open a door with a round knob. (via reddit)
