I too believe that there are cougars here in PA........But.......as soon as I saw this picture, my mind said ...BOBCAT! I think the coloration is right to make it look like a mountain lion, but the tail area has me second guessing. That tail should be thick and noticable if it were a mountain lion, but its not. It is barely noticable. I'm going to have to agree, that this is a bobcat. I know that eventually someday, one will be killed. Be it by a hunter, car, self-defense or whatever, one will be killed and end the mystery. I do know that if I see one, I will shoot it and call the Television stations. So what if I pay a fine. I'll say I was afraid for my life and shot in self defense.
