Reminiscent of this comic, we have pulled the veil back a little further. If Rook wants food, he lets you know. And know. And know. Sometimes when he meows like that we meow back, matching him for length and pitch, but it just turns into a contest and the cat always wins. He's a pro. 

John wants to take a video of Rook and auto-tune it. I think I'd just hit mute.
