Newly born kittens require a diet high in protein, calcium, and plenty of water to ensure an adequate milk supply. You can provide the mother cat with cooked beef, lamb, fish soup, bone broth, or other meats, ensuring that no salt, peppercorns, chili peppers, or other seasonings are added to the food to avoid causing allergies or diarrhea in the kittens.

In addition, goat milk powder can be supplemented to increase protein intake. Mother cats lose a significant amount of calcium during childbirth, so calcium and vitamin supplements are also necessary to help them recover their strength and promote milk production.
