My folks live in their home with heavy exposed beams and three large picture windows across the front looking down the bay at a few islands. The house is placed on top of about a 100' cliff. It was a beautiful summer day and the door to the deck was open. The cat was sleeping in the sun on the living room carpet when my uncle and his dog came in. As soon as the door opened the dog charged the cat. The cat woke and bolted for the open door where it made it's first mistake, it turned right onto the deck with no exit. Out goes the cat, out goes the dog. Seeing the edge of the deck looming, and probably not fully awake, the cat runs up the wall between two windows. When he reached the top of the wall he ran, ran along the underside of this heavy beam for about 6' and then rocketed off the beam into the air Past the living room, past the daylight basement, and over the cliff. There was a bunch of snapping of brush and yowling of cat all the way down the hill. The dog strutted back into the house quite proud of himself. The cat came back after the dog went home, no worse for wear. Well, perhaps his pride was a bit damaged.
