Over a period of more than 20 years, I’ve seen four cougars (“mountain lions” some people call them) in my valley - positive identifications, as they were out in the clear and not partially hidden by
trees or shrubs. First time was midday when i was driving on a quiet highway with a friend, so we were in a car. The big cat was halfway across the highway, and as I slowed then stopped the car, the cat just stood there and looked at us for maybe 10 seconds, then sauntered on its way across the road. He seemed as curious as we were to watch
him. And I’ve heard that they tend to be curious about humans and human activity, but by all accounts are normally shy of people.
You
should be cautious, I think, if you believe there’s one crossing your
land. But attacks on people are
extremely rare. Nearly every time I've heard about one, it’s been in a particular geography (Vancouver Island) that is more than 450 road miles west of where I live. I’ve wondered if there's a particular genetic strain of cougar that lives on Vancouver Island and tends to be less shy of humans than in other parts of our province.
Children seem to be more vulnerable, in the reports I’ve heard about, but still it’s very rare. We have a lot of
deer around here, but in my valley two of the four cougars I’ve seen have been in specific areas where elk herds are present at times. There are stories of attacks on dogs, domestic cats,
chickens, etc - but never anything like that close to me. I remember a couple of news stories of a town about 45-minutes drive from my place where women were astonished to find a cougar in their basements (got in, apparently, through an open window). The two incidents were maybe 15 years apart, and there was no attack by either cat in these cases. I've heard of unarmed adults and children being followed by a cougar without the cat ever attacking and with the cat keeping some distance.
I guess I can sum up by saying that in my neighborhood, if one of us saw a cougar wandering around we’d spread the word to our neighbors. People would probably be cautious but not really alarmed unless the cat started to pick off domestic animals or was hanging out in someone’s
yard. In that case, neighbors would either hunt the animal or leave it to the wildlife officers, if the latter seems like they planned to respond.
