The puma (as it is called in Spanish) inhabits every mainland country in Central and South America, making it the most widely distributed large, wild, terrestrial mammal in the Western Hemisphere, and one of the most widespread on planet Earth. Their range extends further south through Mexico, where they are found in nearly every state, to the Amazon Rainforest and the southern Andes Mountains in Patagonia.
