Now to answer a few questions, yes we have just changed the clocks back around two weeks ago,so there may well be something in that,so i guess when she is waking us up at five am,that was the old 6 am, she does not do it everynight, just most nights, and it was not as soon as daylight saving ended, but you may well have a good point there,nothing else has changed,no new pets, people etc.

She is always a hungry girl,but she is too fat, she is really the heaviest of all my cats apart from Ash, but he is a big cat and he is just fine now, as i have been diligent in getting his weight down, so i don't want to be feeding her any extra, i think i will just make sure there is a little left when we all head off to bed, and if she eats that in the room, fine, if not there will be some left for the morning, that way she may not wake up so early hungry, if that indeed is the issue.

Don't worry she has a litter box and of course water.

Thanks for the ideas, will let you know how it goes, i will try the new regime tonight,wish me luck.
