Mountain Lion/Cat, Cougar, Puma, or Screamer; Can All Name the Same Creature. It is a Regional Difference.
Mountain Lions are very beautiful but illusive. I have only seen one in the zoo because you don't want to see one in person unless you are inside looking out. When we lived in Arizona (about 5,000 feet up and full of boulders) some of the people in our little town would talk of them drinking from their backyard ponds. Or crossing the highway.
