Take great care not to overheat or burn the kittens when they are too young to be able to move away from the heat source. A tall cardboard box makes a safe nest to keep the kittens in until they are several weeks old. Use clean newspaper or cloth for bedding. Feeding You can feed the kittens by bottle or stomach tube. A stomach tube is faster and especially handy with large litters.
Many people enjoy bottle-feeding more, however, because it prolongs contact with the kittens.
Your veterinarian or clinic staff can show you how to use these two methods. Newborn kittens should be fed 6 to 8 times daily. Decrease this gradually to 3 to 4 times daily by the time the kittens are 3 to 4 weeks old. After each feeding, help the kittens urinate and defecate by gently stroking the genital area with a cottonball or tissue moistened with warm water. Persist until they urinate or defecate.
