I could easily waste the whole day watching cat jumps.
I startled a cat in my storage unit one time. It lept over my head and scared me so bad I literally screamed. Then I ran into it again on the outside stairs going up to my apartment. It was so freaked it, it lept about 25 feet over to the fire escape on the building across from mine - one floor lower. It was still about 2 stories up with no way down, so it just sort of ran straight down the wall and went splat on the pavement. Then got up and ran away of course. A freaked out cat can do some absolutely insane things.
