(Newser) – Cats may appear ambidextrous when pawing a ball of string but actually lean lefty or righty when it comes to tough tasks, the New Scientist reports. It comes down to sex: girl kitties are mostly righties and boys lefties, say researchers at Queen's University Belfast in Northern Ireland. Hormone levels may account for the difference—earlier studies have linked prenatal testosterone to left-handedness.
