Kitten yowling in the morning?

Ok, i love my cats, and I have gradually been learning a lot in the cat category here on YA, but I am at my wits end. Every morning, my one cat Dexter howls at my bedroom door to get up and make him breakfast. He always has plenty of food and water (i make sure i give them some before i go to bed) but he wants me to get up every single morning at around 530 (that's when i usually get up for work) to feed him. I try to ignore it so as not to encourage him, but he will literally go on for hours unless i get up. I have tried putting him in the bathroom, the water bottle, everything i can think of. But nothing seems to deter him from his morning feedings. Anyone have any suggestions for me please?
