Okay, I will clarify my last hint further
Species 1 is in the gallery.
Species AND individual 3 is in the gallery.
Species AND individual 4 is in the gallery.
So, by you saying this, are you telling us that #'s 2, 5, and 6 are the ones that have been guessed correctly? You said there were 3 spot-on answers, but did not specify which were the ones correctly guessed.
If that's the case, then I can't believe it. I'm confident No. 1 is a Tibetan golden cat. (Yes, I'm aware it's already been guessed.)
