Silence James (the cat)

Cats are nocturnal, your cat just wants to play or is feeling insecure and wants company.

Solutions:

1. Leave the bedroom door open, your cat may or may not then attack your face as you sleep, worth a shot.
   
2. Open the door and spray the cat with water whenever it wants to get in, after a few nights it'll get the message that bothering you at night is "wrong".
   
3. Buy the cat more interesting things to play with/do at night other than bothering yourself... a massive cat fortress for example.
   
4. Tire the cat out in the daytime and it will be less active at night.
   
5. Your cat thinks that making noise = food and is getting hungary at night, make sure you only feed the cat at a set time twice a day, never feed your cat if it is near the bowl or causing a fuss.
   
   

Good luck and God's speed.
