Ending1: Instead, you'll need to watch and ensure that nothing goes wrong medically. Here are things to look for : [substeps] The kitten is not freed from the birth sac: the kittens usually emerge in individual birth sacs that the mother then licks away. Ending2: A mother will feed her kitten but really gives her the space she needs during the pregnancy. When a kitten is left alone in labor for more than 10 hours, she loses normal maternal control to all aspects of the pregnancy. Ending3: [substeps] If she always tries to head off labor at the same time as she stops nursing, which suggests she's absorbed a bit of milk, she may be a nursing kitten. If that's the case, that can be the sign of a nursing kitten because of the thickened placenta around the breast, also known as her uterus. Ending4: [substeps] Move with her close to the mother when she is pregnant and you will have more freedom during the birthing process. They will just be too fussy to manage once they get born.
