3. I have heard cats going back and forth like that. It can easily sound like humans (or demons!) if you don't know what it is. I was at my lake house one night late in the Fall. I was laying in bed and I swore I heard a woman screaming and moaning. It went on for a couple minutes. My dog wasn't bothered by it, so I assumed it was a wild cat. The next day I listened to animals noises from Northern MN, and the one I was hearing was actually an owl! I don't even want to hear that owl again. However, if you are ever in northern MN, and you hear whistling at night, don't whistle back. That's how the Wendigo finds you!
