It does seem small for a cougar (panther, puma, mt. lion, painer- all the same thing), but does have the proper markings with the exception of the diluted tabby type stripes in the second picture. It also looks a little long legged for a cougar in a couple pictures, but hard to tell. I have a friend with a 'Darwinian' cat. Unusually large breed with extra toes and he is the only domestic cat I have seen that comes close to the same size. I did live in SC sand hills for many years and did see a cougar there twice. The first time I chalked it up as "I must be mistaken". The second time, mentioned it to a store in the area and they said that there was a 'farm' near there that had wild cats and that several years before a few had gotten loose! OMGosh!
I havent read through all of the posts, but if you figure it out, please let us know. I know, as a chicken owner, I should be anti-cat, but I think they are beautiful animals and would love to see one again, although not at night in the woods. I live in TN now and although they say they are or were around here in numbers years ago, and several people swear to seeing one (including my husband), I think I'm out of luck.
