My guys are the same way!!! I can be up till 2 or 3 am, give them a snack, and then at 5:30, Honeybun is standing on my chest bellowing at me because I'm starving him! He's such a demanding boy! With him it's not just a certain time (every morning at 5:30 on the dot (15 mins BEFORE my alarm goes off ), but if I ever lie down to take a nap, or to try to get rid of a headache, when I get up, it's like it's a signal "OH, she's getting out of bed! We have to have food again!" and he'll run around and yell at me until I give him something to eat. And heaven forbid I actually get up and go to the bathroom before feeding them! That's just torture for them!
