Respiratory Infections in Hamsters
Hamsters are susceptible to bacterial respiratory infections (Pasteurella, Bordetella, Streptococcus) and viral infections. Their small body size and high respiratory rate mean infections progress from upper respiratory signs to pneumonia very quickly — sometimes within 24–48 hours. Signs include sneezing, nasal discharge (clear to yellow), wheezing or click sounds during breathing, hunched posture, and rapid shallow breathing. Any respiratory symptom in a hamster warrants same-day veterinary care.
First 3 Steps to Take at Home
- Keep the hamster warm: Sick hamsters lose heat rapidly. Maintain the enclosure at 20–22°C. A gentle heat source under one side of the enclosure allows the hamster to self-regulate.
- Minimize stress: Avoid unnecessary handling. Reduce noise and activity near the enclosure. Stress worsens respiratory illness by increasing oxygen demand.
- Contact the vet immediately: Respiratory infections in hamsters can kill within 48 hours. Don't wait to see if symptoms resolve — call your exotic vet today.
When to Go to the Vet Immediately
- Any nasal discharge or sneezing alongside lethargy
- Labored, rapid, or audibly wheezing breathing
- Open-mouth breathing (always a severe emergency)
- Blue-tinged gums or skin
Follow-Up Care Checklist
- Complete the full antibiotic course precisely as prescribed
- Maintain warmth and minimize stress throughout recovery
- Recheck in 5–7 days to confirm improvement
- Review enclosure ventilation — poor ventilation increases respiratory disease risk
