Isn't that just the way it goes with cats? I often wonder how many "haunted" houses and such are really just cats being cats. I will NEVER forget the time, not long after we moved into our present house, I was sitting watching tv alone at night, looked over and saw two glowing yellow eyes at about "human height" staring in through the screened patio door. Took me a minute to realize one of the black cats had quietly climbed up the screen and was just hanging there staring in at me. *H A !*
Of course that's nothing to the panic of the "man in a hat in my back yard"...which turned out to be a cow.
