Hairy, nasty, and mean?

Not that I get many comments around here, but will any visitor dare to guess what this thing might be?

This is the face of a real animal, not a photoshop. Is that a hatred for all life you see in its eyes? Will it devour your children? Suck out your soul? Should you sleep soundly tonight despite knowing that this thing is roaming out there somewhere in the world?

C'mon, what is it? Guess (no tineye, dammit).
