I can't think of any one good suggestion ... I guess you may just have to put Ally's food in a separate room, and let her in there several times a day to keep her weight up? Only problem with that, is she may end up eating Connor's food that is in the usual place. Hmmmm..... you may have to just plan scheduled feedings with separate bowls and put reduced cal food in Connors, and maybe increase the amount in Ally's bowl? Just a thought... good luck!
