Offer a spacious, secure cage with sturdy bedding, regular veterinary care, and a high‑protein pellet diet supplemented by fresh vegetables. Maintain stable temperature, minimize stress, and provide chew‑proof enrichment to support health and well‑being.

How can you keep a large mouse? - in detail

Keeping a sizable mouse requires attention to space, diet, health monitoring, and enrichment.

Provide a cage that exceeds the minimum size recommendation for standard laboratory rodents. Minimum floor area should be at least 1 ft² (0.09 m²) per mouse, with additional vertical space for climbing. Use a solid-bottom enclosure with a secure lid to prevent escape.

Select bedding that absorbs moisture, controls odor, and allows for nesting. Aspen shavings, paper-based substrates, or coconut fiber are appropriate. Change bedding weekly, removing soiled sections daily.

Feed a balanced diet formulated for larger rodents. Offer a commercial pellet base supplemented with fresh vegetables (e.g., carrots, broccoli) and occasional protein sources such as boiled egg or mealworms. Provide fresh water in a sipper bottle, checking for leakage each day.

Monitor health indicators: weight, coat condition, activity level, and respiratory sounds. Schedule veterinary examinations at least twice a year, and isolate the mouse immediately if signs of illness appear.

Enrichment prevents stress and encourages natural behaviors. Include:

  1. Chewing blocks or untreated wood to maintain dental health.
  2. Hideouts such as PVC tubes, ceramic houses, or folded paper shelters.
  3. Climbing structures like wooden ladders or rope bridges.
  4. Foraging opportunities—scatter small food items in bedding to stimulate exploration.

Maintain a consistent cleaning routine. Disinfect the cage with a rodent-safe solution monthly, rinsing thoroughly before reintroducing the animal.

Record all observations—diet changes, behavior shifts, medical treatments—in a log. This documentation supports timely adjustments and facilitates communication with veterinary professionals.

By meeting spatial, nutritional, health, and environmental requirements, a large mouse can thrive in captivity.
