Both of my cats sleep indoors all night. They have dry food and water available at all times. It doesn't matter what time I go to bed and they settle down with me - the crack of dawn it is their duty to wake me up.
Rascal wants to go outdoors, but he is the more patient one. Patches promptly goes back to sleep after she has done her duty.
In fact she is now snoring on a chair near this computer - I am up - her job is done!
