When Lewis and Clark crossed America, cougars could be found nearly anywhere.  Today, they are found mostly in the western United States and western Canada.  Idaho is the home of many cougars. 

An adult cougar may be five feet long or longer, not including its tail, which is two to three feet long.  A full-grown cougar can weigh about 200 pounds.

Cougars are called by different names in different areas of the country.  Other names are mountain lion, catamount, panther, and puma.
