I'd say even go further and say they differentiate more than that. I remember seeing an adult house cat encounter sheep for the first time. He very clearly and obviously recognized that these were new creatures he'd never seen before. They weren't another cat, nor were they human. His reaction was very interesting to watch. He was extremely leery and cautious of the sheep - but at the same time also very curious about them. After a bit he figured out that the sheep weren't a threat, and that he could approach them and the sheep would more or less just ignore him.

I sometimes wonder if its because they don't pass mirror test and think they are humans.
