The cougar is known by many names. Among them are mountain lion, puma, panther, catamount and deer tiger. It is the largest of the purring cats. Once common throughout North America, its habitat has been reduced to a restricted range west of the rocky mountains with a small remnant population in Florida. The mountain lion ranges in size from six to nine feet from nose to tail with weights between 75 and 110 pounds for females and between 100 and 200 pounds for males. The mountain lion stalks its prey in its favored habitat of rugged terrain with thick cover of forest or brush. Adult mountain lions live within territories of between 25 and 300 square miles which they mark with scrapes of earth, leaves and urine.
