The female cat will continue to produce secretions ten days before giving birth. This is a sign that the female cat is about to give birth and is not about to give birth. A large amount of amniotic fluid will flow out before the female cat gives birth, and the birth will be completed within two hours. The gestation period of a female cat is between 58 and 63 days. If the female cat at home keeps secreting secretions between 30 and 40 days, it may be a sign of miscarriage. It is recommended that the owner take the female cat to the pet hospital for careful examination.
