Goggling Eastern Puma brings up other web sites, however, with varying levels of professionalism or credibility.
The other site, The Cougar Network, is still active, and is reporting the cats expanding range from the West, but offers little about the phenomenon of Pennsylvania cats.
In July and August I received seven different reports, and everyone involved had done a search of some type to compare images of bobcats and pumas.
As you can see from the above images it is very difficult to confuse the two if you have a good view.
However, my friend and I discussed this, and agreed, we saw what we saw, and had it been 40 years ago or four months ago, we knew we saw a coyote.
