Retained Placenta After Birth in Cats: Vet Guide 2025 🐱🚨

Retained Placenta After Birth in Cats: Vet Guide 2025 🐱🚨

By Dr. Duncan Houston, BVSc

🔍 Introduction & Key Points

A retained placenta in a queen occurs when one or more placentas (afterbirth) don’t pass after kittens are born. This can lead to uterine decomposing tissue, infection (metritis), sepsis, and potentially life-threatening illness unless treated promptly.

• ⚠️ Placenta usually delivered within 15 min after each kitten; retained remnants are uncommon but serious.
• 🤒 Watch for signs: foul discharge, fever, lethargy, poor appetite, mother neglecting kittens.
• 🔎 Diagnosis includes physical exam, bloodwork, ultrasound or X-ray.
• 💉 Treatment begins with oxytocin to stimulate contractions; if ineffective, surgical removal or spay may be needed.
• 🩺 Supportive care: IV fluids, antibiotics, pain management, plus monitoring kittens’ care.
• 📈 Prognosis good with early intervention; delayed treatment increases risk of metritis, sepsis, surgery, or death.
• 🛡️ Prevent recurrence by careful breeding, monitoring parturition, and veterinary supervision for at-risk queens.

1. Understanding Normal Placental Delivery

During third-stage labor, the placenta should be delivered shortly after each kitten—usually within 5–15 minutes. In some cases, the queen may eat the placenta, making observation challenging.

Failure to pass the placenta can lead to retained tissue decomposing in the uterus, which fosters bacterial infection and inflammation (metritis/endometritis).

2. Who’s at Risk?

• Queens experiencing dystocia (difficult labor), delayed delivery, or stillborn kittens.
• First-time mothers and those with poor health, uterine inertia, or abdominal abnormalities.
• Litter abnormalities—large litter or oversized kittens increasing delivery strain.

3. Clinical Signs & Warning Symptoms

• 🩸 Foul, greenish-brown vaginal discharge persisting beyond 24 hrs.
• 🤒 Fever, rapid heart rate, dehydration.
• 😿 Lethargy, poor appetite, overall malaise.
• 🐱 Refusal or inability to nurse, neglecting kittens.
• 👶 Distressed or underfed kittens indicating maternal illness.

4. Diagnostic Steps

1. History & exam: date/time of births, discharge, general appearance.
2. Rectal/vaginal evaluation: palpation of uterine enlargement or placental mass.
3. Bloodwork: CBC (neutrophilia, leukocytosis), chemistry (hydration status, organ function).
4. Imaging: ultrasound most sensitive for retained tissue; X‑ray may detect radiopaque material or uterine enlargement.
5. Cytology or culture: if infection suspected to guide antibiotic therapy.

5. Treatment Options

🦠 Medical Management

Start with oxytocin to stimulate uterine contractions (within 24 hrs postpartum).

Concurrent IV fluids, broad-spectrum antibiotics (amoxicillin–clavulanate or cephalosporins), and anti-inflammatories/pain medication.

⚠️ Surgical Intervention

If medical treatment fails or it's late (>24 hrs) or infection is severe, options include:

• Exploratory laparotomy: uterine lavage and manual removal.
• Ovariohysterectomy (spay): often the safest and most definitive treatment, prevents recurrence.

🛠 Supportive & Critical Care

• IV fluids for hydration and toxin clearance.
• Pain relief, anti-inflammatories, heat support, and close nursing care.
• Monitor mother–kitten bonding; supplement or hand-feed if needed.

6. Prognosis & Follow-Up Care

• Early medical management → favorable prognosis.
• Delayed treatment or infection → guarded to fair, depends on systemic involvement.
• After surgery, monitor incision, uterine involution, milk quality, maternal behavior.
• Re-evaluate kittens’ growth, weight, and nursing.
• Antibiotics often continued 5–7 days; NSAIDs as needed.
• Schedule recheck (7–10 days) with abdominal palpation or ultrasound.

7. Prevention & Breeder Advice

• Spay queens not bred regularly to avoid repeated reproductive stress.
• Ensure queens are healthy and dewormed before breeding.
• Have veterinary-supported births with monitoring.
• Time feeding and parturition close to clinic hours.
• Educate breeders on normal vs. abnormal labor and when to seek help.
• Use remote support via the Ask A Vet app for parturition check-ins, red-flag alerts, and postpartum guidance.

8. FAQs

Can I tell if a placenta is retained?

Not always—since queens often ingest placentas. Watch for persistent or foul-smelling discharge and maternal illness.

What if placenta comes out later?

Passing up to 24 hrs later can be okay. Beyond that, risk for infection increases—seek veterinary review.

Will retained placenta affect kittens?

Indirectly—risk of hypothermia, malnutrition, or infection due to maternal illness or inability to nurse.

Should I spay queen if retained placenta occurs?

Yes—spaying during treatment removes source of further uterine disease and protects future health.

9. Caring for Your Queen Postpartum

• Keep placentas in a warm, quiet area.
• Monitor temperature, appetite, discharge, and behavior daily.
• Hand-feed or tube-feed kittens if mother unable to nurse.
• Use E‑collar to prevent wound grooming if spayed or laparotomy performed.
• Log meds, feeding, litter-box habits, weight changes in Ask A Vet app for vet follow-up.

Conclusion

Retained placenta is a serious but treatable postpartum complication. Quick recognition, prompt vet care—including oxytocin, antibiotics, and potentially surgery—gives the best chance for healthy mother and kittens.
