How should field mice be fed? - briefly
These rodents need a diet high in seeds, grains, and insects, complemented by fresh greens and occasional protein sources such as mealworms. Offer small portions twice daily in a shallow dish, and keep clean water accessible at all times.
How should field mice be fed? - in detail
Field mice require a diet that mirrors the natural composition of seeds, grains, insects, and fresh vegetation. A balanced mix should contain:
- 60‑70 % plant material: wheat, oats, barley, millet, dried grasses, and leafy greens such as dandelion or clover.
- 20‑30 % protein sources: mealworms, crickets, dried insects, or low‑fat boiled eggs.
- 5‑10 % fat: small amounts of unsalted nuts or seeds (sunflower, pumpkin) to supply essential fatty acids.
- 5 % moisture: fresh water available at all times; replace daily to prevent bacterial growth.
Feeding frequency should reflect the animal’s high metabolic rate. Offer small portions three to four times daily, removing uneaten food after 30 minutes to maintain hygiene. In colder months, increase caloric density by adding extra fat and protein, while reducing water consumption to prevent freezing.
When providing food, use shallow, chew‑proof containers to prevent spillage and reduce contamination. Avoid items that are toxic or difficult to digest, including chocolate, caffeine, citrus peels, and raw potatoes. Monitor for mold, as it can cause respiratory issues.
Supplementary vitamins and minerals are unnecessary if the base diet includes diverse natural components. However, in captive settings where variety may be limited, a low‑dose multivitamin formulated for small rodents can prevent deficiencies.
Health indicators to watch include steady body weight, bright eyes, clean fur, and active foraging behavior. Sudden weight loss, lethargy, or abnormal droppings signal a need to reassess the diet composition or consult a veterinarian.
