This sunny day, I was out and about destroying perfectly good 2"x4"s with my chop saw. Taking a short break, our little friend "Crackers" came out on the branch of the tree to let me know he was around or possibly calling on his friends that the bird feeder still had seed. A few minutes later, I looked up in the tree to see him sitting on a branch, then I noticed why he was chattering, sitting on the opposite side of the tree and down just a touch an intruder had invaded his territory. Immediately, I thought porcupine. Next thought was dogs and my .22 calibre pistol. Walking over to the tree, I was able to get a better view of the intruder. The "stalker" had come out of the house for the first time this spring, she was hunting and had her prey in sight. The prey also had her in his sight. He stayed on one side of the tree and she the other. I did not time the event, "Crackers" did not want to give away is position and "Lion Cat" was content to wait until "Crackers" got foolish. After sitting on their respective branches for over an hour, they called it a draw. "Mama Cat" crawled down from her twenty foot perch and returned to the house to wait for another day.
