The Dirtbag Diaries podcast had a man on who described a mountain lion that followed him for multiple hours alone on a trail. Apparently, this is something that is not too rare in the PNW. Cats are interested in peoples' headlights and like to follow. My god, that is my worst nightmare scenario, being followed by a cat. That is scarier than a close grizzly bear or rattlesnake encounter.
He had nothing to defend him, so he put his jells and waterbottles around his neck. Never thought of this, but so smart. Cats most commonly kill people by an ambush attack to the neck from behind.
