Chinchilla Retained Fetus & Placenta: Vet Guide 2025 – Expert Vet Insights 🐭🩺

— Written by Dr Duncan Houston BVSc, founder of Ask A Vet —

Introduction

When a chinchilla gives birth, it's vital that all kits and placentas are expelled. Occasionally, fetuses or placental tissue are retained—leading to infection, metritis, and pyometra. This comprehensive 2025 guide helps you identify risks, diagnose effectively, perform safe removal, support recovery, and take preventive steps.

🔍 1. Why It Matters

• A retained fetus (“mummified” or deceased in utero) or placenta can lead to severe uterine infections like metritis and pyometra :contentReference[oaicite:1]{index=1}.
• Even partial retention increases risk—uterine inflammation can become systemic and life-threatening.

🩺 2. Common Causes

• Incomplete birth: Chinchillas may expel kits but not placentas, or miss late-developing fetuses. Females have two pairs of uterine horns—retained tissue may hide in one :contentReference[oaicite:2]{index=2}.
• Stillborn or mummified fetuses: These may not trigger strong contractions and are easily overlooked.
• Uterine inertia or stress: Weak contractions or environmental disturbance during labor :contentReference[oaicite:3]{index=3}.

🚨 3. Warning Signs

• Absence of placentas despite normal number of kits.
• Bloody, mucoid, or foul-smelling vaginal discharge after delivery :contentReference[oaicite:4]{index=4}.
• Fever, lethargy, reduced appetite, decreased milk supply.
• Swollen or doughy abdomen; may avoid nursing kits.

🔬 4. Veterinary Diagnosis

• Palpation: Veterinarian assesses uterus size and detects retained tissue.
• Imaging: Ultrasound and X-rays confirm presence of placental tissue or fetal remains :contentReference[oaicite:5]{index=5}.
• Laboratory tests: CBC may suggest systemic infection; uterine discharge culture guides antibiotics.

🛠️ 5. Treatment Protocol

• Uterine lavage: Gentle flushing under sedation to remove retained material :contentReference[oaicite:6]{index=6}.
• Antibiotics: Broad-spectrum initially, then tailored via culture—commonly 7 to 14 days.
• NSAIDs and fluids: To control inflammation, pain, and support hydration and uterine contraction.
• Supportive care: Promote milk production; encourage kits to nurse or provide formula if mother is sick.

🏠 6. Home Recovery Care

• Ensure calm, clean environment—daily cage changes are essential.
• Continue antibiotics and pain relief per veterinary instructions.
• Monitor discharge—should decrease and appear clearer within 3–5 days.
• Check hydration and appetite; provide soaked pellets or Oxbow Critical Care if needed.
• Consider foster dam or hand-raise kits if mother can't nurse safely :contentReference[oaicite:7]{index=7}.

⏱️ 7. Recovery Timeline

• 0–3 days: Remove tissue, treat infections, manage pain.
• 4–10 days: Reduction in discharge, return of appetite and maternal behavior.
• 2–3 weeks: Uterus returns to normal size; discharge ceases; kits thriving.
• 4+ weeks: Full health restored; consider future spaying if not breeding again.

🛡️ 8. Prevention Strategies

• Monitor birth—count kits and placentas to ensure none are retained.
• Provide calm environment during labor—no disturbances.
• Schedule veterinary check-ups after whelping, especially for first litters or older females.
• Delay breeding until at least 9–12 months to ensure reproductive maturity :contentReference[oaicite:8]{index=8}.

Conclusion

Retained fetuses or placentas in chinchillas can lead to potentially fatal uterine infections. Early detection—by monitoring birth, recognizing abnormal discharge, and seeking timely vet care—can prevent serious complications. With uterine lavage, targeted antibiotics, and careful home care, most chinchillas recover fully. Preventative practices and use of Ask A Vet throughout the process offer guidance and peace of mind.
