Cats have spent centuries acting like gravity is more of a suggestion than a rule. Knock one off a table, and somehow it flips mid-air like a furry gymnast and lands perfectly on its feet—usually looking offended that you witnessed it. Now scientists have finally cracked the mystery behind this feline superpower. By studying cat spines and filming their midair acrobatics, researchers discovered the secret lies in a surprisingly flexible upper spine that twists like a built-in stabilizer. In other words, cats aren’t defying physics—they’re just extremely good at it.
