Screaming sounds coming from the woods at night?

There's a very loud, very drawn out and pronounced scream that comes from my woods occasionally late at night (always after midnight usually). It sounds like a young woman's blood curdling scream, but just somewhere in your mind it doesn't register as a human creating that sound. Someone said it was a fox, but all the fox screams I've heard sounded nothing like it and were very short. Someone said it might be a bobcat, but I could never find a clip of a bobcat making a sort of "screaming" noise. Someone else said it might have been a panther, but just like the fox, it doesn't sound the same. Any ideas?
