Study Reveals How Feline Spines Enable Cats to Land Upright
Researchers from Yamaguchi University published a study in The Anatomical Record examining the mechanics of how cats land on their feet. The team, led by Yasuo Higurashi, analyzed spines from deceased felines and observed live cats dropped from low heights onto cushioned surfaces. They discovered that cats' thoracic spines twist more easily than their lumbar regions, allowing sequential rotation during falls. While the research doesn't fully explain the phenomenon, it provides new insights into feline biomechanics. Experts note that cats may combine multiple motions, including tuck-and-turn and bend-and-twist techniques, to achieve their signature landing.
