I'll never deny that an escaped or loose pet could run loose from time to time.It's happened in the past but the cats always go to people,where they can get food.It happened about a year ago with some other type of exotic cat,not far from Wilkes-Barre.It's extremely improbable that a released animal will head to the wilderness and stake it's claim there.It's even more improbable that it won't leave any evidence behind.I suppose it's exptremely unlikely but not impossible that one will travel from out west,cross the Mississippi,reach Pa and then turn around and go back home without leaving a trace.Possible but doubtful.It's far more probable,considering the lack of any hard evidence that all of these mountain lion and balck panther sightings are nothing more than bobcats,labs and house cats being mistaken for mountainion lions.
