After a mother cat gives birth to a cub, it usually takes some time to recover, and it is best not to get pregnant again immediately. Usually, female cats have to wait at least 6 to 8 weeks to get pregnant again. This period of time can make the mother cat's body fully rest and recover, and ensure that she has enough nutrition and physical strength to cope with the next pregnancy and childbirth. In addition, frequent pregnancy and childbirth may have a negative impact on the health of female cats, increasing the risk of illness and abnormal cubs.
