Recently my cat has adopted the habit of squawking really loudly when she wants to be fed. She typically does this early in the morning. Of course that's not the part that makes me happy. What makes me happy is that when I tell her to stop squawking, she says "I'm not squawking, I am Tiggering!" It turns out she thinks she sounds like a mighty tiger when she squawks, and the only tiger whose name she knows is Tigger. So she made a verb of it, which I thought was quite sophisticated for a cat.
