What kind of feline is this one photographed near Decatur, Illinois?

According to the Eastern Puma Research Network (EPRN): “This mystery cryptid animal was caught on film by the wife of an EPRN associate member, who had gone hunting at 0530 hours in November 2004…The animal was filmed at 0547 hours in an area that empties into Sangamon Run…..EPRN knows it is not a black puma nor a housecat due to its features. It was estimated to weigh 40 – 60 pounds.

I have my own thoughts, but, first, what do you think?
