The cougar belongs to the genus Puma, and for all its size it does not roar like lions, tigers, or leopards; instead it screams, growls, and purrs, sitting genetically closer to smaller cats than to the roaring Panthera line that includes the tiger, jaguar, and snow leopard. Cougar, mountain lion, puma, panther, and catamount are all one species; the "Florida panther" is a rare regional population, not a separate kind. Adults measure 3.5 to 5.5 feet in body length plus a heavy 2-to-3-foot tail, stand 24 to 35 inches at the shoulder, and weigh from about 64 to 140 pounds, big males sometimes topping 200. The plain tawny coat — no leopard rosettes or cheetah spots — suits shadowed forest and canyon country, while powerful hind legs, a counterbalancing tail, retractable claws, and padded feet make it a superb stalker.
