They already sort of have set meal times; they get 1/2 a can (each) friskees at shot time (1/4 fresh and 1/4 frozen, so it lasts longer), and 1/4 can around +6 (work days it's +4 before I go to work). Usually the smaller portion gets eaten immediately; they larger sometimes lasts until the next meal. With two boys, it's hard to strictly ration one--I really suspect Cass eats more of the food than Benny (instead of 1.5 cans each/day, I think Cass eats about 2 and Ben about 1). I don't know that there's much more adjusting I can do with food--he's back up to a good weight and seems stable. (Started at 16 pounds, down to about 8.5 at worst, back up to health 11 now). I rotate 5 kinds of food, all right at 6% carb.
