Sounds like Jagger. Hendrix will sleep through the night, but not Jagger. He won't wake me up now until 6am though and he's up long before that as I do hear him having a snack, playing with toys etc.
The only thing you can do is ignore her. Do not get up as you are reinforcing the behaviour by giving her the desired reaction. I used to literally shut my bedroom door, and even though he would be at the door scratching, it was marginally better than having him sweeping anything and everything off the chest of drawers or attacking my feet.
If he starts wailing earlier than 6am I also ignore him and I don't get up until he's been quiet for a bit so he doesn't think I'm getting up as a reaction to his wailing for attention.
I can now leave the bedroom door open all night, I don't think I'll ever get him to be quiet until after 6am (although my target is 6.30am) but 6am is better than some of the times he used to try to get me up to play or get food etc. I always leave dry out for him at night otherwise that is another trigger for him to try to get me up.
Have to laugh though as last night his slumber was disturbed by Jon coming home at 1am and he was back in the cat tree for a nap before I left for work
he can dish it out but doesn't like being woken up by either of us!!!
