Postpartum Discharge in Cats: Causes, Care, and Nursing

Red lochia, characterized by its dark red hue, marks the early stage of a cat's postpartum lochia expulsion, typically occurring within the first week. Serous lochia, on the other hand, appears lighter in color, indicating a decrease in blood but still containing a significant amount of uterine and vaginal mucus. This is followed by whitish lochia, which signifies that there is no blood present in the discharge.

The duration for which a cat expels lochia can vary greatly. During this period, cats may also clean themselves by licking. However, it's important to note that the cat's cervix is open, making them more susceptible to retrograde infections, which can lead to endometritis and vaginitis.

Therefore, pet owners should frequently change the bedding, ensure proper nutrition to boost the cat's immune system, and closely monitor any changes in the color, odor, and amount of the lochia.

When a cat's lochia does not cease, and there is a continuous discharge, it indicates that the lochia is not expelling properly. This condition, known as retained lochia, refers to the persistent flow of pale or dark red, turbid fluid from the uterus postpartum.

This can lead to a gradual weakening of the cat's body and spirit, with the cat frequently licking at the vulva. In such cases, the owner should:

1. Inspect the birthing area and the cat's vulva for any puslike discharge, observing the color and consistency of the pus.

2. Look for any signs of rupture or swelling around the vulva.

3. Check for redness or the presence of pus in the mucous membranes.

Retained lochia is more common in cats with weak constitutions or those suffering from diseases. Treatment should involve a combination of清热利湿 (clearing heat and dampness), 活血化瘀 (activating blood circulation and removing blood stasis), 收敛止带 (constricting and stopping vaginal discharge), and the use of Western medicine for antibacterial and antiphlogistic effects, along with systemic treatment to prevent the spread of infection and appropriate energy supplementation.

The use of traditional Chinese medicine, such as Qinggong liquid for uterine irrigation, can also treat retained lochia. The liquid should be warmed to body temperature before being directly infused into the uterus through a catheter. For large cats, the dosage is 2030ml per session, while for small to mediumsized cats, it is 58ml, or adjusted according to the size of the uterus. (This procedure should be performed by a professional veterinarian.)

Western systemic therapy can also aid in the expulsion of lochia. Medications such as glucose and sodium chloride, glucose, cefazolin sodium, analgin, and vitamin injections can be used. (Dosage should be as prescribed by a doctor.)

When a cat exhibits retained lochia postpartum, it is crucial for the owner to seek veterinary care promptly.
