well i will say this about the mountain lion:

very smart, very agile, very silent. they don't like people. the PGC sais the same thing up here in pennsylvania "there aint no (wild) mountain lions in pennsylvania", well i beg to differ. there have been many many sightings and they are here. as far as fighting with dogs, i will put my cane corso mastiff up against any mountain lion any day of the week!!! they were bred to bring down stag and to fight lions (african lions) back in the roman empire
