When Mattie Grace and her babies were with me, I'd go to the store and buy fresh chicken livers and boil them for her. I mixed them with canned kitten food. Catnapper is right though. Feeding her kitten food is a great idea. It will help put some pounds on her and might even increase her milk production. Are her teats full?? You might want to check to make sure she HAS enough milk.

If the babies are crying and seem hungry, you might want to get a can of liquid KMR, a mama's milk supplement and feed them. Because Mama is malnourished, it could be her milk supply isn't what it should be and that's why the babies are hungry.
