Never mind the cougar, it's that sasquatch dude you should worry about. Seriously, as far as people, livestock, and house pets are concerned, you will have more problems with wild dogs and coyotes than you will with a puma.
Agreed. A cougar was spotted up in northern lower Michigan this summer, near Glen Lake. If people kill their native prey, like rabbits, coons, etc., they will start invading human habitats. Otherwise, they want nothing to do with people.
