Yes, I've seen and heard many here out West.

The most terrifying sound they make comes from females in heat.

It's a sort of scream that sounds like a teenage human girl screaming defensively. When you hear it in the middle of the night from a dark, wooded canyon, it really does make the hair on your neck stand up!

Man, that sounds like something you'd never forget.
Then you run to rescue the teenage girl and there's a dern female Cougar in heat layin out waitin for ye!

Tonight it is going down to about 2 deg., at about 10 to 10:30 I will go see if the coyotes are screaming. First time I heard them I thought it was a girl being knifed to death in my backyard, now I take the dog out so I can watch his hackles go strait up.
