I've heard something like that before 40+ years ago when I lived in Napa Valley of CA. A buddy and I had buddy hiked up to a high point near basalt lava flow cliffs overlooking Calistoga CA. We cooked our meals, got a buzz on, enjoyed the city lights of the valley down below, and bedded down for the night. We were awakened in wee hours of the night by blood-curdling screams immediately outside our flimsy nylon tent. No idea whether it was one cat or two cats having an encounter. My bet is our high point camp site was territory of some lynx (or some other large cat) and he was not happy with our choice of camp sites. My companion who was Vietnam vet said he hadn't been that scared since undergoing middle of night mortar attack. We just shook like leaves in our bags too afraid to look outside or shine a light to see what the heck it was. It eventually stopped but it was real hard going back to sleep. Of course our house cat makes similar noises when a neighbor's cat comes in the yard. We like to refer to it as kitty Kibuki theater because that's what it sounds like. That whole region of Napa Valley was burned up in wild fires from year or two back. I wonder what it looks like now.
Skiguy's YouTube video is definitely what we heard - very scary. My skin crawls to remember it. We thought screaming sounded like someone torturing a baby. We didn't have you tube back in those days. I had to go to the library to research our experience.
