Ahhh nuu!
It's unusual that there's a female. The way it was explained to me, it's usually young males moving into inhabited areas because the big old toms will tolerate as many females as their territory can possibly support. I wonder if this means the population's starting to get out of hand. The two they found in Discovery Park (downtown Seattle) were both young males.
Part of that might be because females home ranges are vastly smaller in area than male territories. And males are very territorial while females are not. The males' territories will often over lap female home ranges. Males in neighboring territories are usually unrelated and they tend to want to avoid other territories, which keeps conflicts down. (of course, that doesn't always happen) These male territories can be very, very large and over-lap human habitat as well. That's why we're seeing more and more cougar attacks in just the last few years I suspect. But as far as humans being natural or typical prey, prey recognition is a
learned behavior so typically humans aren't a part of their diet, as are deer, rodents and so forth.
This bit about their territories is why it's unsuccessful usually to re-locate them. The fish and game could plunk a cougar in the middle of another male cougar's territory unknowingly and cause a big ruckus between them. They will get very aggressive when one is in another's territory. So, the new comer might well leave and return to the area where it was caught. Relocating bears is also next to impossible...they can take them away miles and miles and they'll return to the same area every time.
I'll bet depending on where everyone lives, there have been cougars watching you when out on a hike or camping somewhere. I am quite certain that the places I use to hike in regularly had cougars around and aware of my presence.
They just didn't go after me...luckily for me. lol.
