I am not claiming to believe that Mountain Lions have been breeding here in PA for over a century without there being any evidence. All I am saying is that I found that piece of scat and it looks way to big to be from a coyote or bobcat. The tapered ends suggest a coyote, but with a drier diet Mtn. Lion scat can become tapered as well. I have never heard of a 7 1/2 in. coyote turd, but if anyone has please make me aware of it. It is also true that coyotes could have deer hair( from carrion) and bone fragments in their scat as well. Also take into consideration that when I found the scat is was very old and dried out, so the volume most likely decreased. The head of the eastern cougar research network is paying for the DNA test just based off the pictures he saw. I am not making a bull **** claim, but I am putting the evidence infront of you and asking for some opinions.
