Ever wonder how a cat would react to microgravity?
Apparently cats have an automatic "righting system" built into them which makes sure they always land on their feet. In the absence of gravity though, the cat feels like it is constantly falling and can't "land", so their righting system puts them into an endless spin. Cool huh?
Also (via NASAwatch), in case you prefer dogs to cats: http://www.youtube.com/watch?v=cwwlkF0C04k&eurl=
