Under normal circumstances, cats will give birth to babies on their own, but if the cat is unhealthy or has other factors, it may cause dystocia. At this time, the owner needs to help the cat give birth. Normally, when a cat gives birth, it will bite off the umbilical cord and eat the placenta. However, if there are many kittens, do not let the female cat eat all the placenta. This can easily cause diarrhea and the owner needs to throw away the placenta.
