This depends on the eating situation of the female cat. Generally, the female cat will defecate 1-2 days after giving birth. If the female cat does not defecate for more than 48 hours, the female cat will need the help of the owner. The owner can put the female cat in a quiet room to relax the cat's mood to promote defecation; the owner also needs to let the cat drink more water and eat more food containing moisture to relieve dryness.
