They are agile tree climbers. Males are generally larger than females, averaging 130 to 150 pounds in weight and ranging in length from 72 to 90 inches. Females average 65 to 90 pounds. Pads on the forefeet are larger than those on the hindfeet. Claw-marks seldom show in the tracks of this species.
Deer are their favorite prey.
They have also been known to prey on beaver, porcupines, rabbits, skunks, domestic livestock, pets and other small mammals, birds, and even fish. Dens can be found in any concealed, sheltered spot. Male mountain lions roam widely, females less widely, especially when the cubs are small. Adult male home ranges often encompass more than 100 square miles. Adult males use their hindfeet to scrape duff into a small pile to declare their territory.
