How to Create a Healthy Mouse Habitat


Creating a healthy habitat for your pet mouse is easy. You will need a simple cage, bedding and a few accessories to supply food and water. Mice are simple, low-maintenance pets but they do require some occasional attention. Multiple mice can share a cage but a single mouse is also an option. Females coexist well but cannot be combined with males unless you want offspring.

Cage and Space Requirements

An individual mouse requires a 5 gallon cage to have ample space for running. A 10 gallon cage works well for multiple mice without having more than five total. Glass aquarium cages work well as do wire cages with a plastic bottom. The bottom of some wire cages slides out for easy cleaning. Wire cages also have better ventilation for your mouse. The wire must have a tight design specifically for small rodents or your mice will escape through the gaps. Mice can fit through tiny holes. The cage must eliminate all escape routes.

Bedding and Habitat

Bedding is important for comfort, burrowing and absorbing urine and feces. Paper and paper shavings are acceptable for mice. Aspen shavings also work well for bedding. Paper is easy to remove and replace and standard newspaper is a good nontoxic option. Add entertainment and hiding spaces to the habitat for mental health and stress reduction. Add a wheel, small plants and rock features that provide a safe hiding area.

Dietary Needs

Mice do not require large quantities of food. Commercial rodent pellets and food blocks are available through pet stores. Add leftover vegetables to the cage on occasion as well. Carrots, lettuce and basic table scraps are acceptable. A small amount of peanut butter is a real treat as well. Only add small bits of table scraps because mice will store uneaten portions and they will dirty the cage. Maintain a constant supply of fresh water inside the cage. Bottle style watering systems hang on the outside of the cage and have a nipple for drinking. This prevents the mice from defecating in the water.

Cage Maintenance

Cleaning the cage is an absolute necessity. Replace the litter and wipe down the cage floor several times each week. Removing feces, urine and leftover food will create a healthy habitat for the mice. It also reduces odors and prevents flies and insects from gathering in the cage.


  • Only clean with nontoxic cleaning solutions. Basic water is adequate for regular cleaning. Use a rag with white vinegar for sanitizing and odor removal. Toxic cleaning solutions may affect the health of your mice.
