The Puma (Puma concolor), also known as the Cougar or Mountain Lion, is a large, solitary cat found in the Americas. It has a vast range, from Yukon Territory in Canada to the southern Andes of South America. Their primary food is deer, but they hunt prey in a range of sizes, from insects, mice, and rabbits, domestic cats, domestic dogs, alpaca and on up to Bighorn Sheep and Elk. They are secretive cats who usually avoid people, and attacks on humans are rare. Due to overhunting and continual human development of puma habitat, populations have dropped in many parts of their historical range, although recent conservation efforts have allowed the puma's numbers to improve in some areas. Though frequently lumped in with larger cats, the puma is distinct in that it cannot roar, and makes vocalizations much more common to small cats.
