Ok, I’ll play. First, I’ve been told by a nature expert from the Maine woods that fisher cats are not proven to make any sounds. And that the sound of a woman screaming is the gray fox (or red fox?). According to him, when claims are made about fisher cats, no one can say that they actually saw the fisher cat make the sound. Instead they hear the sound, then soon after see a fisher cat in the area. He said they don’t have physical evidence in their body to make sound (like vocal cords, or whatever the animal equivalent is.)
Anyway, if it is a dramatic sound, of varying notes and screeching, then I would say fox.
If it is a lower single raspy pitched RAAANT RAAANNT, but REALLY LOUD, then I don’t know what the heck it is, but I hear it ALL THE TIME!
