Man...I don't know what to think of these pics. First let me start off by saying that I think that there are deffinitely cougars in Pa so I'm not trying to be a doubting thomas here. Personally I think that the pic is that of a bobcat. Yes, the color matches a Mt. Lion to a T, but there are other characteristics that make me not so sure. The tail for one seems way too skinny to me to be a lion. The base of the tail would be as thick as your wrist and it deffinately wouldn't be white underneath as in the pic. The tail is also at least 3 feet long in a lion and curves out behinda lion, however in this pic you don't see any tail in the opening where one should be indicating the tail can't be more than 12 inches or so. You can also clearly see the tufts of hair on the cheeks that is common in bobcats but not there at all in Mt. Lions. Mt. Lions also don't have clearly defined white bellies and chins as in the pic but I've seen bobcats that do. Like I said, I have seen lions in Pa and firmly believe they are here, I just think some people want to see proof so bad that they tend to be biased when looking at pics.Sorry, but my vote is bobcat. I know I'm stirring up a hornets nest here but this is just my opinion based on what I see.

Here is a pic pointing out what I'm talking about just to clarify.
