Discipline and integration of cats?

Can anyone help me? Marshall lately has been banging on the door from 3:15 A.M. to early morning, and meowing. He has plenty of food and water, the litter box is nearby. But it's annoying and gives me headaches right in middle of peaceful sleep. I've tried to ignore him but he acts up. Is there any way to discipline him to stop and be patient. I know he wants full freedom to be with me. But it won't happen until the cats are fully integrated-Sweet Pea, besides didn't fight the three days before Easter, didn't fight them a few days after Easter, when lately Wylie hissed at her yesterday-yet. We've tried vanilla extract and baby powder, and nothing worked. Is there any resolve to this? Please help.

ignore the cat.

Reply:For the cat that is banging on the door. Sounds familiar. I suggest either of the following or a combination. For HOURS before you go to bed, keep the active, do NOT let him sleep and about an hour before, No activity, but no sleeping either. Worked for my two little boy cats and I still do that. Also, when he bothers you at night (I also did this with the boys) I'd open the door just a tiny bit and give him a squirt or two with water and say in low tone "NO" or "STOP IT" Now I can leave my door open and they normally will just go to sleep or play elsewhere. I still keep the water bottle handy in case they want to claw the laundry basket or get into the closet. This is just normal for people who are owned by cats. I have three.
Reply:Try bathing them together. Take them all in the bathroom and wash them. Not only will this traumatic experience bring them closer, but now they will all smell the same.
Reply:Maybe they just need a place to sleep that is there own.. Like a basket. My mainecoon need that.
