If you've ever seen a cat fall from any height, you've observed that they tend to land on their feet—not all the time, but more often than not.

This has led actual rocket scientists to drop cats as a physics demo (don't try this at home), writers to explain cat-dropping physics, and has even spawned The Buttered Cat Paradox (a thought experiment that could, at least in theory, create infinite spin).

National Geographic brings us a short Animal Mysteries clip that does a good job explaining what you need to know about how cats perform this mid-air feat. The most interesting part of this video is a late-'80s study showing that cats that fall from higher floors in buildings tended to survive more than those on lower floors. Why? Take a look:

Please don't try to reproduce these results at home. Your cat will not appreciate it.
