Mountain lions, pumas, panthers... Whatever you call them, big cats once roamed every U.S. state. But they’ve long been a ghostly presence east of the Mississippi.

People still report seeing cougars in the South. Take Todd Lester. He’s a former president of the Eastern Cougar Foundation. We hear about his close encounter.
