What should be done if mice are born? - in detail
When newborn rodents appear, first confirm species, age, and number of individuals. Identify the mother’s condition and verify that she is capable of nursing. Separate any visibly ill or weak pups for immediate attention.
Prepare a secure, temperature‑controlled enclosure. Maintain ambient temperature between 28 °C and 30 °C during the first week, using a heating pad or lamp with a thermostat to prevent overheating. Provide nesting material such as shredded paper or cotton that can be reshaped without harming the young.
If the mother refuses to nurse or is absent, substitute with a commercial rodent formula. Warm the formula to 37 °C, feed using a small pipette or specialized nursing bottle, and limit each feeding to 0.2 ml per pup every 2–3 hours. Gradually increase volume as the pups gain weight.
Monitor weight daily with a precise scale; a gain of 2–3 g per day indicates adequate nutrition. Observe for signs of dehydration, respiratory distress, or abnormal behavior. Administer isotonic saline drops if dehydration is suspected, and seek veterinary care for any persistent illness.
Document each litter’s date of birth, parental identification, health observations, and interventions. Review local regulations concerning rodent breeding; obtain permits if required and ensure humane disposal of excess or non‑viable offspring.
