    I made an animation to explain how cats can initiate rotation and turn around during free fall, without violating the conservation of angular momentum:

    Some footage of real cats:

    A talk at MIT dealing with the falling cat at time 20:30:

    Well done. Somebody add some text and make this a FAQ so that we clink to it in the future.

    Thanks. Here some more videos on this:

    This one in zero-g starts a bit mean but at 0:12 you can see the cat spin up very fast and make several full turns within a few seconds.

    Probably the first attempt to show how a cat does it. But the frame rate is much to low to see anything.
