Cats

Cats are watching you closely from behind their topaz eyes, calculating your every move and indeed bending your will to their own. Cats are the true gods of the Yrth, but they've allowed us to believe that they need our help, our coddling, our inane talking to them in silly voices. Well, that just ain't so, sister.

Unbeknownst to most humans, many cats can talk and can understand human speech. In fact, cats can do a lot of things you silly-ass humans wouldn't think they could do. Shows what you know, Yrth-monkey.

You've gotta love the old adage:
When the squirrels are away, the Cat will play.
