Help! My cat won't stop waking me up stupid EARLY

I have had my cat, Maya, for five years, and I love her to pieces… 23 hours a day. That other hour, though, I want to chuck her across my bedroom and accompany her flight with a loud string of expletives. She used to wake me up around six for breakfast which was fine. But now she starts at 5, or 3, or 1 effing 30 in the morning, picking at whatever might be lying around, and singing the song of her people.
