Those are some BIG ole cats. Is their natural prey all gone?
More likely their natural prey is living in this person's yard. They're lounging like they just ate.
Why else would they overcome so-called fear of man?
In my experience mountain lions don't have any fear of humans at all. What they do fear is guns, and they can actually smell if you have one. There's an old mountain trick where you carry gunpowder soaked with a few drops of oil in a sock when you're hiking to keep the panthers away.
Unless perhaps they were raised around people as kittens? What drove them out of the wild and into a neighborhood? Seeing them in my front yard would scare the hell out of me...
As their habitat shrinks, some of them adapt to living in suburbs and surrounding areas that used to be their home. I bet there aren't in stray dogs or cats in that neighborhood.
I once caught a Bobcat stealing a chicken in the dead of winter. He never made a sound I could hear, but my dog's nose told me he was there. I had a rifle, but I looked at him and he looked at me (with the dead chicken in his mouth) and I relaxed and told him to go ahead and take it. We've claimed and/or destroyed so much of their living area that I can't deny them a bird now and again....especially in the winter when pick'ins are slim. He turned around and trotted off just like he understood me. If I'd started to bring the rifle to bear, he would have dropped his meal and run for his life. They really are that smart.
The mountain lions in the park have been known to chase prey onto the road on a curve, with one cat on either side, so a car will hit the dear, hog, or whatever they want for dinner. Then they rush in, grab it, and drag it away. Your average house cat is a moron compared to these guys.
Emotionally, I can handle a human intruder easier than those stray cats.!.!.!
You should probably know that they can smell fear too. ;)
