I was parked on a back road one evening glassing for deer when I saw a doe in the road in the rear view mirror. Then a house cat started to cross the road about 40 feet closer, and the doe started snorting and stamping, and coming toward the cat. Cat turned and ran back the way it came, and the doe stamped and snorted as she watched the cat leave. Doe then turned and ran up the hill the opposite way. Was fun to watch. The doe jumped up from her bed the next morning, and I froze and looked at her. She stamped at me several times, trying to figure out what I was, then turned and ran off. It was either sex Whitetail in that muzzle loader area at the time, but I couldn't bring myself to shoot such a feisty critter. Turned out to be my only opportunity that year, but even if I had known, I still wouldn't have shot her.
