Lol! How I wish I could do this, but it would wake up my downstairs neighbours. I too have problems sleeping through the night since we adopted our cat Gaia. While she is adorable, she is also incredibly smart and annoying at times. She has learned that bitting is really effective to wake us up and get attention. First she starts really gently, and then if we ignore her she bites harder until you start reprimanding her and she won, you're up. She will often try this at 2h00 am, 5h00 am, 6h00 am, etc. So she lost her 'bedroom privileges', but now she keeps scratching at the door. We're trying real hard to not feed her before it's time to get up, because that would just reinforce the behaviour. Earplugs help. I may also try to let her back in the room and use the water spray to get her to stop bitting. She already gets a good 20 minutes of play time before bed and a bit of dry food.
For biting, I have noticed that Moosey really responds to a firm "no". Usually she will just look at me like I broke her little heart. If she starts to bite I say "NO, we don't bite" and she usually stops. Same for Zigs.
For the vacuum cleaner thing, that wouldn't work for us. The door she scratches is right next to the door to the bathroom, so if I put it behind our door, it would block the bathroom and if my roommate wanted to go to the bathroom the vacuum would block the door and he wouldn't be able to open it.
For the wedging door thing, that wouldn't work either because of my roommate and it doesn't stop her from meowing, which is does very loudly.
We had problems again last night. I am absolutely exhausted today.
