KC: I was maybe 11 or 12 years old when I heard my first Cottontail Rabbit "scream"!
I was sound asleep one summer, early morning, with my bedroom window open. My bedroom was right over the family garden plot and the "screaming" woke me up - I had NO idea what it was.
I look out my window to see a Cottontail Rabbit flopping and half jumping right below me. And to my amazement I also see a Weasel with a jaw death grip on the Cottontails throat!
This went on for a couple of minutes until I could get my trusty Remington bolt action Model 511 Scoremaster 22 L.R. and whacked the Weasel amidships. The Rabbit did not survive the attack from that Weasel either.
At the shot the rest of my family arose as they had been awakened by the "screams" of that Cottontail. We were all puzzled and stunned at the noise and by the attack by the much smaller Weasel on the Cottontail.
Nature!
