The puma,also known as a cougar, mountain lion, mountain cat, catamount or panther, depending on the region, is a mammal native to the Americas. This large, solitary cat has the greatest range of any large wild terrestrial mammal in the Western Hemisphere, extending from Yukon in Canada to the southern Andes of South America. An adaptable, generalist species, the puma is found in every major American habitat type. It is the second heaviest cat in the American continents after the jaguar. Although large, the puma is most closely related to smaller felines.
