Mountain lions once roamed nearly all of the United States. They were prized by hunters and despised by farmers and ranchers who suffered livestock losses at their hands. Subsequently, by the dawn of the 20th century, mountain lions were eliminated from nearly all of their range in the Midwest and Eastern U.S.  Mountain lions require a lot of room. Only a few cats can survive in a 30-square-mile (78-square-kilometer) range. They are solitary and shy animals, seldom seen by humans. While they do occasionally attack people...usually children or solitary adults. Statistics show that, on average, there are only four attacks and one human fatality each year in all of the U.S. and Canada. - courtesy of National Geographic

Mountain lions do not like to share their territory and are constantly on the lookout for invaders. This powerful predator roams the Americas, where it is also known as a puma, cougar, and catamount. This big cat of many names is also found in many habitats, from Florida swamps to Canadian forests.
Mountain lions like to prey on deer, though they also eat smaller animals such as coyotes, porcupines, and raccoons. They usually hunt at night or during the gloaming hours of dawn and dusk. These cats employ a blend of stealth and power, stalking their prey until an opportunity arrives to pounce, then going for the back of the neck with a fatal bite. They will hide large carcasses and feed on them for several days.
