Mouse Habitat

Mice are active, curious, and love to climb and explore. Their habitat should be designed to accommodate these natural behaviors, providing plenty of space and enrichment to keep them happy and healthy.

An infographic showing the ideal habitat setup for mice, including enclosure type, bedding, enrichment items, and environmental conditions.

Enclosure​

Bigger is always better, especially for a group of female mice.

  • Size: A 10-gallon tank is the absolute minimum for 1-2 mice, but a 20-gallon long tank or larger is much better. For groups of 3-5 females, a 40-gallon breeder tank or a large DIY bin cage is recommended.
  • Type:
    • Glass Tanks: Excellent for providing deep bedding and preventing escapes. Requires a secure wire mesh lid for ventilation.
    • Wire Cages: Can be a good option, but bar spacing must be 1/4 inch or less to prevent escapes. Look for cages with a deep plastic base to allow for adequate bedding.

Bedding​

Mice love to burrow and build nests.

  • Depth: Provide at least 2-3 inches of bedding, though more is always better.
  • Safe Bedding Types:
    • Paper-based bedding (Kaytee Clean & Cozy, Carefresh)
    • Aspen shavings
  • Nesting Material: Provide soft materials like tissue paper, paper towels, or hay for them to build nests.
  • Unsafe Bedding: NEVER use cedar or pine shavings (toxic oils), scented bedding, or fluffy cotton material (can cause impactions).

Enrichment: Keep Their Minds Busy​

Mice are intelligent and need a stimulating environment.

  • Wheel: A solid-surface wheel is a must. A 6.5-inch wheel is a good size for most mice.
  • Climbing: Provide ropes, ladders, and branches for climbing.
  • Hides: Offer multiple hides like cardboard tubes, small boxes, and wooden houses.
  • Chews: A variety of chews is essential for dental health. Offer cardboard, apple wood sticks, and other safe wood chews.
  • Foraging: Scatter their food around the cage instead of using a bowl to encourage natural foraging behaviors.

Environment​

  • Temperature: Keep the room at a stable temperature between 65-75°F (18-24°C).
  • Location: Place the cage in a relatively quiet area, away from direct sunlight, drafts, and other pets.
  • Odor: Male mice have a stronger odor than females. More frequent bedding changes may be necessary for males.
