I'm not fat!

My grandparents keep saying I'm fat. And they do it in the room too -- like I can't hear! I guess, well, fine. I'll admit it. I've been eating too many Whisker Lickin's lately and also taking too many long naps. But I love Wisker Lickin's! And I love naps! I need more exercise. I think I shall go chase a sparrow now. If someone would just remove that pane of glass, I would catch the sparrow...
