I've heard a rabbit scream twice in my life. One night in the summer I woke up and one was screaming in the woods next to the house. A fox probably got it. I knew the sound because I've heard a recording of it, and IIRC it was called a "Dying rabbit call". I guess it's used in predator calling. Second time was a real small young one that got behind a small wire mesh fence behind the garage with only one way out. I cornered it out of curiosity and snatched it up and was gonna put it in the woods. That thing began screaming and it wasn't even hurt. Guess they also scream out of terror.
