I was just looking out on my back garden and spotted a cat on next door's shed roof. It was on the edge of the roof and posturing in such a way as to suggest it was contemplating a jump to my shed roof 8 level feet away. As I watched it took off and caught the roof with it's front claws and the rest of it's body hit the side of the shed. It then scrambled onto the roof, went to the edge, jumped down and ran off into the bushes. I never for one moment thought it would make the jump and I was partly right.
