I am also becoming aware of early morning lovies, kisses, and bites can be a sign of them being hungry. Although I leave out a tray of food for all to eat out of, sometimes they want more than just dry food. Then I have to get up (usually have to anyway) and get them, especially Tiger, some canned food to mix in with their tray of dry. Usually after eating, as well as my own apetite being taken care of, we can go back to sleep.
