There’s a saying that cats always land on their feet. Most oft he time this is true, but what’s even more remarkable is how cats manage this acrobatic feat. Essentially, cats keep their total angular momentum at zero at all times by bending their body sharply, and then twisting each half on two axes that combine to cancel out the rotation of the whole.
If this sounds too scientific, the simple answer is that cats twist their bodies around so their feet always land on the ground first. After all, if you landed on any other part of your body, it probably wouldn’t feel as gentle as landing on your feet.
