Years ago I asked a older warden that had a display set up at the fiar if there where mountain lions in Pennsylvania?
He clearly stated "NO" and there have not been any in the state for many many years.
I said "So if I shoot one it would not be a problem".
To which he replied ,"No that would be illegal"
I then countered, "But you said they did not exist"
He then grew very silent.
I leave it at that, combined with my own sighting and the denial of Government agency's on many fronts, I suspect there is much more to Puma sightings in PA we never hear about.
