I would imagine you do have cougar up there. Most of the time, they stay away from people but we had one three or four years ago that was walking right through yards. He/she got hit by a car, probably one that was old or ill.
There's a hunting season on them in the forest where we ride. And since hound hunting is banned, their numbers are probably growing because I don't know how you'd find one otherwise.
I'm told the only way to ever see them is to look behind you. ;~)
