Cini will sleep until 6.30am or so and then she begins to whinge. She's on her bed in the lounge and the door to the hallway is shut during the night, so she knows she gets fed at 7am and will get let out to toilet before that. If she's any earlier, which especially happens in summer with such early light, she'll come into bed after being outside. Never before toilet time though, she peed in bed once. In fact, if she ever stayed asleep in her own bed 'til late, I'd think she was sick or something. Our cat will come on the bed at the same time and sit on top of me so close that when she sneezes, I wear it all on my face. She's a persian, so she has a little trouble with her nose.
