Symptoms of retained placenta in female cats:

1. Continuous dark green discharge: Most female cats discharge secretions within 24-48 hours after giving birth. The discharge just after giving birth is dark green, but it usually turns to rust color within 24 hours.

4. The secretion lasts for 48 hours.

5. Fever: If the female cat’s body temperature is too high, it may represent an infection.

6. Drowsiness.
