I deer-hunted a steep ridge in West Virginia, sneaking to my post by flashlight. Settling against a stout tree, I switched off the light and waited for the first hint of daylight to break the inky darkness. Suddenly, something nearby began screaming, enough to make my hair stand on edge. I didn’t know what it was, but you can bet the safety on my rifle instantly clicked to “fire.” This video reveals a likely source — a cat in heat. Be it mountain lion or bobcat, you have to hear it to believe it.
