I was standing at the kitchen sink when I heard the thundering horde descending from the second floor. I turned around in time to see the youngest female hit the throw rug in front of the outside door, surf it across the vinyl kitchen floor into the leg of the kitchen table which catipulted her into the dining room where she hit the floor at high speed and tore up the stairs. This all happened in a split second. The chasing male had stopped at the kitchen doorway because he knew the game plan. When she came out of the dining room he pounced, missed and also tore up the stairs. The cat asleep in the living room never twitched an ear.
