I must say i agree with MServantOh dear little Lily, she sounds like a live wire. :lol3: Not what you need when your patience is thin from lack of sleep.
Do take care with her and using the water spray technique as, althought she currently seems defiant and not phased, it can result in anxiety for many cats. Even if you have used this method successfully before. It may seem exhausting when the main thing you want it rest and sleep but diverting her scratching and other behaviours you wish to stop to less precious / easily damaged surfaces or appropriate play can be more effective in the long run and help to build a really strong and positive bond between you and your cat (rather than the big human who is always telling her off). There are a few articles here on TCS about how this works if you haven't seen them, but perhaps for when you have managed to get a little rest.

you can make a very nervous cat with the spray bottle. I've never used it. I find it a bit cruel.
