A very unusual way for a cat to jump. It is very refined and elegant and as you can see the cat balances perfectly as she lands on the top of the fence. At this point she momentarily stands on her hind legs, vertically and in perfect balance and then rocks forward to land in perfect horizontal alignment with the floor. It is very strange and beautiful I have to admit. My guess is that the cat has been doing this an awful lot and has had the time to refine her jump to such an extent that she has ended up making it a work of art.
