I agree that her having human ears is not proof of her not being Faunus. I concede that she does have a feline appearance about her. And she displays a Faunus friendly attitude,

That said, I so far don't accept that or a twitching of her bow as absolute proof of her being Faunus.

There was at least one other than Velvet who raised a hand in answer to Prof. Ooblek's question, indicating that Faunus are openly accepted at Beacon Academy as students. So there would be no obvious reason for Blake to hide her Faunus status.
