As of 2014, the heaviest cougar on record is one from Arizona that tipped the scales at 276 pounds. Most cougars are much smaller than this; males weigh about 125 pounds, and females weigh about 100 pounds. The average size of cougars varies slightly in different regions.
Despite being only about 100 pounds in weight, cougars can kill prey up to six times their size. Cougars hunt a variety of animals, including deer, moose and elk. Blessed with exceptional athleticism, cougars can jump up to 15 feet in the air and climb trees with ease. Often, cougars drop down on their prey from above.
