🔍 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 :contentReference[oaicite:3]{index=3}.
• 🤒 Watch for signs: foul discharge, fever, lethargy, poor appetite, mother neglecting kittens :contentReference[oaicite:4]{index=4}.
• 🔎 Diagnosis includes physical exam, bloodwork, ultrasound or X-ray :contentReference[oaicite:5]{index=5}.
• 💉 Treatment begins with oxytocin to stimulate contractions; if ineffective, surgical removal or spay may be needed :contentReference[oaicite:6]{index=6}.
• 🩺 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 :contentReference[oaicite:7]{index=7}.
• 🛡️ 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 :contentReference[oaicite:8]{index=8}. In some cases, the queen may eat the placenta, making observation challenging :contentReference[oaicite:9]{index=9}.

Failure to pass the placenta can lead to retained tissue decomposing in the uterus, which fosters bacterial infection and inflammation (metritis/endometritis) :contentReference[oaicite:10]{index=10}.

2. Who’s at Risk?

• Queens experiencing dystocia (difficult labor), delayed delivery, or stillborn kittens :contentReference[oaicite:11]{index=11}.
• First-time mothers and those with poor health, uterine inertia, or abdominal abnormalities :contentReference[oaicite:12]{index=12}.
• Litter abnormalities—large litter or oversized kittens increasing delivery strain :contentReference[oaicite:13]{index=13}.

3. Clinical Signs & Warning Symptoms

• 🩸 Foul, greenish-brown vaginal discharge persisting beyond 24 hrs :contentReference[oaicite:14]{index=14}.
• 🤒 Fever, rapid heart rate, dehydration :contentReference[oaicite:15]{index=15}.
• 😿 Lethargy, poor appetite, overall malaise.
• 🐱 Refusal or inability to nurse, neglecting kittens :contentReference[oaicite:16]{index=16}.
• 👶 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 :contentReference[oaicite:17]{index=17}.
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) :contentReference[oaicite:18]{index=18}.

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 :contentReference[oaicite:19]{index=19}.

🛠 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 :contentReference[oaicite:20]{index=20}.
• 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 :contentReference[oaicite:21]{index=21}.

What if placenta comes out later?

Passing up to 24 hrs later can be okay. Beyond that, risk for infection increases—seek veterinary review :contentReference[oaicite:22]{index=22}.

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 :contentReference[oaicite:23]{index=23}.

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.
