Should I be increasing just fat intake, or mainly fat intake, and some extra carbs+protein to my mice diet? I have two mothers taking care of 14 3 week old babies. The smallest was found being eaten this morning. I feed them two hand-fulls of dog food, rice, flax, millet and daily scraps from meals every day. Any suggestions on what and how much to feed these mice that could get them full? They seem to eat a LOT and never stop.
