Check the rodent’s temperature with a rectal thermometer, keep it warm and hydrated, and contact a qualified veterinarian immediately for diagnosis and treatment.
What should you do if a rat has a fever? - in detail
A rat with an elevated body temperature requires immediate attention. First, confirm the fever by measuring rectal temperature with a small digital thermometer; normal range is 99‑101 °F (37.2‑38.3 °C). If the reading exceeds this, isolate the animal to prevent stress and contagion.
Next, provide a warm, quiet environment. Place the rat in a cage with a low‑profile heating pad set to low, covered with a towel to avoid direct contact. Ensure the enclosure remains dry and free of drafts.
Hydration is critical. Offer fresh water in a shallow dish and add an electrolyte solution formulated for small mammals if available. Provide moist foods such as boiled egg whites, plain yogurt, or pumpkin puree to encourage fluid intake.
Monitor for additional symptoms: lethargy, loss of appetite, nasal discharge, or changes in stool. Record temperature and behavior twice daily. If the fever persists for more than 24 hours, rises above 105 °F (40.5 °C), or the rat shows worsening signs, contact a veterinarian experienced with rodents promptly.
When a veterinary appointment is arranged, bring the following:
- Recent temperature readings.
- A list of foods and water consumption.
- Any medications or supplements currently administered.
- Details of the rat’s habitat, including bedding and temperature settings.
The veterinarian may prescribe antipyretics approved for rodents, such as low‑dose acetaminophen or specific NSAIDs, and may conduct diagnostic tests (blood work, cultures) to identify underlying infections. Follow the prescribed dosage precisely; do not administer human medications without professional guidance.
After treatment begins, continue supportive care:
- Maintain a stable, warm environment.
- Offer frequent, small meals of easily digestible protein and carbohydrates.
- Keep the cage clean to reduce bacterial load.
- Re‑measure temperature every 6‑8 hours to track response.
If the rat recovers, gradually return to normal housing conditions and observe for any relapse over the next week. Implement preventive measures: regular cage cleaning, balanced diet, and routine health checks to reduce the risk of future febrile episodes.
