Cougar mating scream. House cats also scream but it doesn't stand the hair on the back of your neck in quite the same way.

Beat me to it. I had a cougar couple years ago, killing my animals, thought it was bobcats. My neighbor killed the mountain lion while it was strolling off my place in mid-day.

Which got me to researching them - old Texas history is replete with nape-hair-raising accounts of the puma scream. I never saw or heard it, wish I had.

I'm gonna have to agree with Concentric Circles on this one... check out these sounds I found at a Cougar/Mountain Lion/Puma website...

These sounds are loud, so make sure your speakers are turned down. I don't wanna cause anyone to get scared for nothing.

Hear the screams of two female mountain lions in estrous
