Early in the morning, around sunrise, the lovely little fur-ball that slept by you night decides to get up. She trots over to her bowl, which is empty ... Then, she comes back into the bedroom and meows at the top of her lungs - for the sole purpose of waking your lazy butt up to get her something to eat!

A back-up waking device in feline form. Gentler when it initially goes off, but if you press the snooze bar, is subsequently harsher (depending on how hungry it is).
