How should domestic mice be fed? - briefly
Pet mice need a nutritionally complete mouse pellet as the staple, complemented by limited fresh produce (e.g., carrot, apple) and occasional protein treats such as boiled egg or mealworms; fresh water should be supplied continuously via a sipper bottle. Feed small portions twice daily, removing uneaten food to maintain hygiene.
How should domestic mice be fed? - in detail
Domestic mice require a balanced diet that supplies protein, carbohydrates, fats, vitamins, and minerals in proportions that support growth, reproduction, and longevity. Commercially formulated rodent pellets are the most reliable source of complete nutrition; they should constitute the majority of the daily intake. Pellets provide consistent nutrient levels, reduce the risk of deficiencies, and limit excess calories that can lead to obesity.
Supplementary foods can be offered in limited quantities to provide variety and enrichment:
- Fresh vegetables (e.g., carrots, broccoli, spinach) – 1–2 g per mouse per day, washed and cut into bite‑size pieces.
- Fresh fruit (e.g., apple, banana) – 0.5 g per mouse per day, seed‑free, given sparingly due to sugar content.
- Protein treats (e.g., boiled egg white, cooked chicken) – no more than 0.2 g per mouse per day.
- Small amounts of whole grain cereal or oats – 0.5 g per mouse per day.
Water must be available at all times in a clean, leak‑proof bottle. Replace the water daily and disinfect the bottle weekly to prevent bacterial growth.
Feeding schedule should follow a consistent routine. Provide the measured portion of pellets each morning; remove uneaten fresh foods after 2–3 hours to avoid spoilage. Monitor body condition weekly; adjust portions if mice become overly thin or gain excessive weight.
Common pitfalls include:
- Offering unlimited seeds, nuts, or dried fruit, which are high in fat and can cause obesity.
- Using canned or processed human foods that contain salt, spices, or preservatives harmful to rodents.
- Allowing access to toxic plants (e.g., avocado, onion, garlic) or chemicals (e.g., cleaning agents).
For breeding colonies, pregnant or lactating females need increased protein (approximately 20 % of the diet) and additional calcium sources such as crushed eggshell or mineral blocks. Weanlings require finely ground pellets or soft mash to facilitate consumption.
Regular health checks should accompany the feeding plan. Observe for signs of malnutrition (e.g., runted growth, hair loss) or digestive issues (e.g., diarrhea). Adjust dietary components promptly and consult a veterinarian experienced with small mammals if problems persist.
