Is your cat more active at night?

My kitty, Oscar, seems to be more active at night in my opinion, though I swear I think his personal schedule moreso is "let me be up and about while the human-man is trying to sleep or very grouchy!". The worst thing he does late at night is that he will meow non-stop outside my door at 2 or 3 am and finally I will get up, open the door, let him in and guess what? He meows to go out if I close the door.

And yes I make sure he has food in his dish and is watered. I think he just likes tormenting me when I want to sleep. I still love him though
