It could be possible that the the Faunus are related to the Grimm, somehow. If they were a mix of human and Grimm is would explain a) their animal characteristics (the Grimm also resemble animals) b) why they're so descriminated against by humans.

I don't know how how humans and Grimm could have mixed, but if they did, it was a long time ago. The Faunus shown so far look mostly human, and bear no resemblance to Grimm outside of their shared animal traits.
