I saw that video and it was truely amazing. When I was a teenager I had a cat that would perch on top of the cabinets next to the back door. One morning before school, my boyfriend just walked in the back door to pick me up to walk to the bus stop. My cat pounced down on his head and dug in the claws on all four feet! The commotion had everyone in the house in the kitchen. One of us held onto the cat while the rest of us slowly removed his feet from the poor guys head. Needless to say, he never did that again!! The same cat used to perch on the edge of the roof of the house and wait for any unsuspecting dog to wander into the yard. He would wait for it to get close enough then pounce down and ride on its back all the way down the street, claws dug in. The poor dog would be howling all the way!!
