Flexible feline spines shed light on “falling cat” problem

Why do falling cats always seem to land on their feet? Scientists have been arguing about the precise mechanism for a very long time—since at least 1700, in fact—conducting all manner of experiments to pin down what’s going on. The research continues, with a paper published in the journal The Anatomical Record reporting on new experiments to analyze the flexibility of feline spines.

We covered this topic in-depth in 2019, when University of North Carolina, Charlotte, physicist Greg Gbur published his book, Falling Felines and Fundamental Physics. For a long time, scientists believed that it would be impossible for a cat in free fall to turn over. That’s why French physiologist Etienne-Jules Marey’s 1894 high-speed photographs of a falling cat landing on its feet proved so shocking to Marey’s peers. But Gbur has emphasized that cats are living creatures, not idealized rigid bodies, so ...
