What should I do if a mouse is not eating? - briefly
First, check the cage for stressors, correct temperature, fresh water, and replace old food with a variety of high‑fat, protein‑rich options while observing for any signs of illness. If the mouse continues to refuse food after 24–48 hours, consult a veterinarian for a thorough health assessment.
What should I do if a mouse is not eating? - in detail
When a mouse stops consuming food, the first step is to verify that the environment is suitable. Check temperature, humidity, and lighting; rodents thrive at 20‑24 °C, 40‑60 % humidity, with a regular light‑dark cycle. Excessive heat, drafts, or constant illumination can suppress appetite.
Next, inspect the cage for cleanliness. Accumulated waste, spoiled bedding, or contaminated water sources introduce stress and illness. Remove all soiled material, replace with fresh, low‑dust bedding, and provide fresh, filtered water in a bottle or bowl that is cleaned daily.
Assess the diet. Offer a balanced chow formulated for mice, ensuring it is fresh and free from mold. If the mouse is accustomed to a specific brand, introduce a small amount of the new food alongside the familiar one to encourage trial. Occasionally supplement with safe treats—small pieces of fresh fruit, boiled egg, or a few seeds—to stimulate interest, but avoid overfeeding.
Observe for signs of disease. Look for lethargy, ruffled fur, nasal discharge, ocular irritation, or abnormal breathing. Palpate the abdomen gently for swelling. If any of these symptoms appear, isolate the animal and consult a veterinarian promptly; loss of appetite often precedes more serious conditions such as respiratory infections, gastrointestinal blockage, or metabolic disorders.
Consider stress factors. Introduce new cage mates gradually, limit handling to short, calm sessions, and minimize loud noises or vibrations. Provide enrichment items—running wheels, tunnels, chew blocks—to reduce boredom, which can lead to reduced feeding.
If the mouse continues to refuse food after environmental, nutritional, and health checks, perform a short fasting period (12‑24 hours) under veterinary supervision, then re‑introduce a bland, easily digestible diet such as plain boiled oatmeal or mashed sweet potato. Monitor intake closely; a gradual return to normal consumption indicates recovery.
In summary, address environmental conditions, maintain hygiene, verify diet quality, watch for illness, reduce stress, and seek professional veterinary advice if the problem persists. Prompt, systematic action restores appetite and safeguards the mouse’s wellbeing.
