How should you set up a mouse cage? - briefly

Use a solid base of clean, absorbent bedding, a secure, ventilated lid, and place food, water, and enrichment items (e.g., a wheel) so they are accessible but separated from waste. Check the cage daily for cleanliness, replace bedding regularly, and ensure all components remain safe and functional.

How should you set up a mouse cage? - in detail

A mouse enclosure must provide safety, ventilation, enrichment, and ease of cleaning. Begin with a cage of appropriate size; a minimum of 30 × 30 × 30 cm per mouse ensures adequate space for movement and nesting. Choose a model with a solid base, secure latch, and escape-proof mesh.

Essential components

  • Solid flooring covered with a thin layer of absorbent bedding (e.g., aspen shavings) no thicker than 2 cm.
  • Nesting material such as shredded paper or cotton for building shelters.
  • A hide box or PVC tunnel to offer a dark, secure area.
  • Chewable items (wood blocks, cardboard) to satisfy dental wear.
  • A water bottle with a metal sipper tube, positioned low to prevent tipping.
  • A stainless‑steel feeder or a heavy ceramic dish to hold food.
  • An exercise wheel of appropriate diameter (minimum 8 cm) that rotates freely and lacks gaps.

Setup sequence

  1. Place the cage on a stable, level surface away from direct sunlight, drafts, and loud noises.
  2. Lay the bedding evenly across the base; avoid excessive depth that can retain moisture.
  3. Position the hide box in one corner, ensuring the entrance faces away from the cage door.
  4. Attach the water bottle securely; test the flow to confirm a steady drip without leakage.
  5. Fill the feeder with a balanced rodent diet; replenish daily.
  6. Install the exercise wheel, checking that the axle spins smoothly and the rim has no openings larger than 0.5 cm.
  7. Distribute chewable items throughout the enclosure to encourage exploration.
  8. Add a small amount of nesting material near the hide box for building.

Maintenance guidelines

  • Spot‑clean droppings and urine daily; replace soiled bedding weekly.
  • Sanitize the cage with a mild, non‑chlorine disinfectant monthly; rinse thoroughly before re‑adding bedding.
  • Inspect all accessories for wear; replace broken wheels, damaged mesh, or cracked water bottles immediately.
  • Monitor humidity; maintain levels below 60 % to prevent mold growth in bedding.

By following these specifications, the enclosure will meet the physiological and behavioral needs of laboratory or pet mice, reduce stress, and simplify routine husbandry.
