Pet Mice are captivating to watch, simple to care for, and undemanding companions, making them wonderful pets for many. While they can be a little nervous and are more delicate to handle compared to larger rodents like rats, pet mice can become comfortable with gentle handling, especially when they are tamed from a young age.
Pet mice boast a delightful variety of colors and have short fur. Their distinctive features include rounded ears and long tails with sparse fur. As nocturnal creatures, mice are most active during the night, often sleeping during the day, which can be a unique consideration for pet owners. Their care routine primarily involves providing high-quality rodent food and consistently cleaning their living space.

Understanding Mouse Behavior and Temperament
Mice are inherently social animals, thriving in the company of their own kind. Keeping a pair of females is often the simplest setup, and a small group of females can also live harmoniously together given sufficient cage space. Male mice, however, can be territorial. Pairs of males should only be housed together if they are littermates raised together from birth and provided with a spacious cage that allows for individual territories. Introducing unfamiliar males is likely to result in fighting. Furthermore, unless you intend to breed them, avoid housing males and females together to prevent unwanted litters of baby mice.
It’s crucial to keep pet mice separate from other household pets to minimize stress and prevent potential injury. However, mice can learn to be comfortable around humans and many can become hand-tame with patient and gentle interaction. Mice that are not accustomed to handling, or those handled roughly, may bite out of fear or defensiveness. Improper handling can also lead to injuries. Even a short fall can cause significant harm to a mouse, and picking them up by their tail is extremely harmful and should never be done. When handling a mouse, it’s best to do so just above your lap or a soft surface to cushion any potential falls.
Mice are generally quiet pets, although their nighttime activity might be noticeable if their enclosure is placed near your sleeping area. Expect to dedicate a few hours each week for feeding and maintaining a clean habitat for your pet mice.

Mouse Size Details
From nose to tail, mice typically measure between 5 to 7 inches in length. Their bodies alone are approximately 3 inches long, and they weigh around one ounce. Pet mice reach maturity at about 2 months of age.
Housing Your Pet Mice
The appropriate cage size depends on the number of mice you plan to keep. A 10-gallon aquarium with a secure mesh top or a wire cage of similar size is generally suitable for one to four mice. Wire cages offer superior ventilation, but ensure that the bar spacing is narrow enough to prevent your mouse from escaping. Cages with horizontal bars and multiple levels are ideal as they provide opportunities for climbing and exploration, enriching their environment. It’s best to avoid cages with wire floors, as solid flooring is much more comfortable for mice’s sensitive feet.
Modular plastic cages designed for hamsters can also be used for mice. However, these can be more difficult to clean thoroughly and sometimes lack adequate ventilation. A determined mouse might even chew through the plastic components.
Mice universally enjoy exercise wheels with solid surfaces (wire wheels can be harmful to their feet), tunnels, and various toys, including:
- Wood chew blocks to help maintain dental health
- Small cardboard boxes for exploration and nesting
- Ladders to add vertical dimension to their space
- Cotton ropes for climbing and play
- Paper towel or toilet paper tubes for enrichment
- Small willow balls for chewing and play
In addition to toys, a proper habitat should include a nest box or another type of shelter where mice can retreat to feel secure and reduce stress. Position the cage in a location away from drafts and direct sunlight to maintain a stable and comfortable environment for your pet mice.
Substrate and Bedding Needs
For the cage floor, use several inches of aspen shavings or undyed paper bedding to provide a soft and absorbent base. It is important to avoid cedar and pine beddings as the oils in these woods can be harmful to mice’s respiratory systems. For nesting material, offer strips of facial tissue, paper towels, or hay, allowing them to create comfortable nests. Unless nesting material becomes heavily soiled, clean it out only every month or two, as frequent changes can disrupt their sense of security. Bedding should be changed weekly, and the entire enclosure should be scrubbed with mild soap and water during this time to maintain hygiene.
The 9 Best Toys for Mice—Some Even Better Than Toilet Paper Rolls

Mouse Diet and Hydration
Pet mice should be fed a commercially formulated rodent pellet that contains approximately 16% protein, 18% fiber, and 4% fat. Always follow the feeding guidelines on the food packaging and confirm the appropriate amount with your veterinarian. Mice naturally graze throughout their waking hours and may even wake up for snacks, so it is important to ensure food is always available. Keep a small ceramic bowl filled with a day’s worth of food in their habitat at all times. Discard any uneaten food after 24 hours and replenish the bowl daily to maintain freshness and prevent spoilage.
You can supplement your pet mouse’s diet with seeds and grains, as well as small amounts of fresh fruits and vegetables. Suitable options include broccoli, peas, apples, carrots, and cucumber. Consult with your veterinarian about the appropriate quantity and frequency of these supplemental foods, as it can vary depending on a mouse’s size and activity level. Place fresh foods in a separate dish from the pellets and remove them after a few hours to prevent spoilage. The best time to feed fresh supplements is in the evening as mice become active and begin foraging for food.
Always provide fresh water for your pet mouse. A water bottle attached to the enclosure is the most hygienic option as it minimizes contamination. However, also provide a water dish in the enclosure until you are certain that the mouse is consistently using the water bottle. Refresh the water daily to ensure it is clean and accessible.
Common Health Issues in Pet Mice
Tumors are frequently observed in mice and are often malignant and life-threatening. Signs of tumors include visible lumps or swellings, lethargy, and unexplained weight loss. Surgical removal may be possible for some tumors, but recurrence is common.
Another serious and prevalent health condition in mice and other pet rodents is wet tail, a gastrointestinal disease typically caused by bacterial overgrowth in the digestive tract. Wet tail can progress rapidly and can be fatal if left untreated. Symptoms include diarrhea, lethargy, loss of appetite, and difficulty walking. A veterinarian specializing in exotic animals can treat wet tail with antibiotics.
Veterinary Care Tip
It’s important to note that not all veterinarians are experienced in treating mice. Before bringing pet mice home, ensure that there is a veterinarian near you who is qualified to provide care for these small animals.
Training and Taming Your Mouse
To begin taming your pet mice, spend time near their enclosure regularly so they become accustomed to your presence and scent. Offer favorite treats, such as millet or sunflower seeds, from your hand. This often encourages mice to approach and eventually walk onto your hand. From there, you can gradually start to pick them up. When lifting a mouse, gently scoop it up by cupping your hand underneath its body, avoiding squeezing or tightly gripping it. Patience and gentle interaction are key to building trust and taming pet mice.
Exercise Needs
Mice require regular physical activity to prevent obesity and maintain overall health. Providing a sufficiently large enclosure equipped with an exercise wheel will generally meet their activity needs. You can also offer supervised out-of-cage playtime in a secure, enclosed area, such as a kiddie pool with high sides that mice cannot climb. Always supervise mice closely when they are outside of their enclosure to ensure their safety.
Grooming Practices
Mice are naturally clean animals that groom themselves frequently, so they do not require baths. However, occasionally, they might need assistance with dental grooming. Mouse teeth grow continuously throughout their lives and are typically worn down by gnawing on food and other objects. In some cases, teeth can become overgrown, requiring trimming by a veterinarian to prevent discomfort and feeding difficulties.
Costs of Keeping Pet Mice
The primary ongoing expenses for pet mice are food and bedding. On a monthly basis, you can expect to spend approximately $20 to $30 on these essentials. You will also need to periodically replace chew toys and other habitat items as they wear out, which might average around $20 each time. Additionally, remember to budget for routine veterinary checkups and potential emergency veterinary care to ensure the health and well-being of your pet mice.
Pros and Cons of Pet Mice
Pet mice offer numerous advantages as pets. They are quiet, require minimal space, and are social creatures capable of forming bonds with their owners through gentle handling. However, they are delicate and require careful handling. Additionally, their lifespan is relatively short compared to some other pets.

Purchasing or Adopting Pet Mice
Pet mice are commonly available at pet stores. However, adopting from a reputable breeder or rescue organization is often a preferred option. Breeders and rescues can typically provide more detailed information about the animals’ health and history, and they may have already begun the taming process. Expect to pay between $5 and $10 on average for a pet mouse, although the price can vary based on factors such as age and breed.
Mice are among the most affordable pets, with initial costs ranging from $5 to $10. Most pet stores carry them. When selecting a pet store or breeder, choose one that separates males and females at a young age to prevent accidental breeding. Mice can reproduce as early as 6 to 8 weeks old, which is very stressful for the female and not recommended.
Reproduction and Breeding Considerations
Local veterinarians specializing in exotic animals can often recommend reputable breeders or rescue organizations in your area. The main advantage of choosing a breeder is the wider selection of younger animals, while rescue groups often have a good selection of mice needing homes. Before choosing a mouse, observe them and ensure they are housed in a clean environment.
When selecting your pet mouse, look for an animal that is alert, has a smooth, clean coat, and healthy pink skin. The eyes and nose should be clear of any discharge, and the mouth and anal area should be clean and dry. Their droppings should be well-formed and not watery. While a mouse’s breathing will be relatively rapid, it should not be labored or noisy.
Confirm that the seller keeps male and female mice separated, as mice can begin reproducing at around 6 to 8 weeks of age. To avoid unintentional breeding, only keep mice of the same sex together.
