What do domestic white mice eat? - briefly
Domestic white mice thrive on a diet of nutritionally complete rodent pellets, complemented by modest portions of fresh fruits, vegetables, and occasional protein sources such as boiled egg or mealworms.
What do domestic white mice eat? - in detail
Domestic white mice kept as pets require a balanced diet that supplies protein, carbohydrates, fats, vitamins, and minerals in proportions similar to those of wild conspecifics. The core component is a commercially prepared rodent pellet or block formulated for laboratory or pet mice; these products contain 18‑20 % protein, 4‑6 % fat, and essential micronutrients, and they are designed to meet the species’ nutritional standards without excess calories.
Supplementary items can broaden the diet and provide enrichment:
- Fresh vegetables: small portions of carrot, broccoli, spinach, or cucumber, washed and chopped finely. Offer no more than 10 % of total intake to avoid digestive upset.
- Fruits: apple slices (seedless), banana, or berries, limited to occasional treats because of high sugar content.
- Protein sources: boiled egg white, cooked chicken breast, or mealworms, provided in very small amounts (1‑2 % of diet) to prevent obesity.
- Fiber and chew material: plain, unscented paper, wood blocks, or hay encourage dental wear and gastrointestinal motility.
Water must be continuously available in a clean bottle with a metal spout to prevent contamination. Change the supply daily and sanitize the bottle weekly.
Feeding schedule varies with age:
- Neonates (0‑3 weeks): rely exclusively on dam’s milk; if orphaned, use specialized milk replacer administered every 2‑3 hours.
- Weanlings (3‑4 weeks): introduce softened pellets and soft vegetables; feed 3‑4 times daily.
- Adults (≥6 weeks): provide ad libitum access to dry pellets; supplement with fresh foods 1‑2 times per week.
Health considerations dictate exclusions. Avoid toxic foods such as chocolate, caffeine, alcohol, raw onions, garlic, and any processed human snacks containing salt, sugar, or artificial additives. Monitor body condition; excess weight indicates over‑feeding or insufficient exercise, while rapid loss suggests illness or inadequate nutrition.
Regularly inspect the feed for spoilage, mold, or pest infestation. Rotate stock to use older batches first, and store unopened packages in a cool, dry environment. By adhering to these guidelines, owners can sustain optimal growth, reproductive performance, and longevity in domestic white mice.
