Can't see how those could even be close to a cougar. Tail length is too short. Also, Just look at the body of the back animal. It basically is extended out like what a dog does to smell a potential mate. You can also see the collar extending down below its neck. The body length is also too short to be that of a large cat. If this was a cougar the tail would be a lot longer. You can also tell my the slender size of the cats hindquarters. A wild cat has to have much larger hindquarters to take down the prey it catches. I've seen cougars in the wild, many times close up at the zoo close to my house and too many that I care to admit at the bars here in Chicago. Seems to be a couple hounds to me.

2 Lunger is right in all his findings as well. People may call animals black panthers but they don't exist. I think that the percentages lead to this picture being of dogs. Personally, I'd rather catch 2 sasquatches on camera mating, now that would be a good thread to read!
