Field mice, with their adorable twitching noses and scurrying antics, might seem like charming companions. If you’re pondering the question, “Can I Keep A Field Mouse As A Pet?”, you’re likely drawn to their wild charm and perhaps seeking a pet that’s a little different from the usual hamster or gerbil. The idea of domesticating a creature from your backyard can be intriguing, but it’s essential to understand the realities and responsibilities involved. This guide will delve into everything you need to know about keeping a field mouse as a pet, ensuring you’re well-informed before making this decision.
Understanding Field Mice: More Than Just Pests
Before you decide to welcome a field mouse into your home, it’s crucial to understand what they are and how they differ from domesticated pet mice.
What Exactly is a Field Mouse?
Field mice, also known as wood mice or deer mice, are wild rodents belonging to the Apodemus genus. They are typically larger than house mice, with longer tails and more prominent ears and eyes. Their fur is usually brown, allowing them to blend seamlessly into their natural woodland or grassland habitats. These creatures are naturally adapted to survive in the wild, foraging for food, building nests, and evading predators.
Field Mouse vs. Pet Store Mouse: Key Differences
While both are rodents, there are significant differences between field mice and the domesticated mice you find in pet stores (Mus musculus). Pet store mice have been bred for generations to be docile and comfortable around humans. Field mice, on the other hand, are wild animals. This distinction is crucial because it impacts their behavior, temperament, and care requirements in captivity. Wild mice haven’t undergone domestication, meaning their instincts are geared towards survival in the wild, which can present unique challenges when keeping them as pets.
Is Keeping a Field Mouse as a Pet Ethical and Legal?
One of the first and most important considerations is the ethical and legal aspect of keeping a field mouse as a pet.
Ethical Considerations
Removing a field mouse from its natural environment can be ethically questionable. Wild animals are part of their ecosystem, and taking them into captivity disrupts this balance. Furthermore, field mice are not naturally accustomed to human interaction, and confinement can cause stress and anxiety. It’s vital to consider whether keeping a wild animal captive is truly in its best interest.
Legal Ramifications
Laws regarding keeping wild animals vary greatly depending on your location. In many areas, it’s illegal to capture and keep wild animals, including field mice, without proper permits or licenses. Before attempting to keep a field mouse, research your local wildlife laws and regulations. You might need to contact your local wildlife agency or animal control to determine the legality in your area. Ignoring these regulations can lead to fines or legal repercussions.
How to (Carefully) Capture a Young Field Mouse (If Permitted)
If you’ve considered the ethical and legal aspects and are still determined to keep a field mouse, capturing a young one is crucial for potential domestication.
Timing is Everything: Age Matters
The age at which you capture a field mouse significantly impacts its ability to adapt to captivity and bond with humans. Baby mice that are still entirely dependent on their mothers (pink and hairless) are too young and unlikely to survive without maternal care. However, there’s a short window of opportunity when they are young enough to adapt but old enough to be independent.

The ideal time to capture a field mouse is when it has fur but its eyes are still closed. At this stage, they are beginning to wean but haven’t yet developed a strong fear of humans. Once their eyes open and they become more aware of their surroundings, they will be much harder to tame and more prone to stress in captivity.
Humane Capture Methods
If you decide to capture a young field mouse, use humane methods to minimize stress and injury. Avoid snap traps or glue traps, as these are cruel and can severely harm or kill the mouse. The best option is to use a live animal trap, also known as a humane trap.
These traps are designed to capture animals without harming them. Bait the trap with appealing food like peanut butter or seeds and place it in an area where you’ve observed field mouse activity. Check the trap regularly and, if you catch a mouse, proceed with caution.
Setting Up the Perfect Habitat for Your Field Mouse
Once you have (hopefully humanely and legally) acquired a young field mouse, creating a suitable habitat is paramount for its well-being.
Cage and Bedding: Mimicking Nature
A glass aquarium or a wire cage with a very fine mesh (to prevent escapes) of at least 10-20 gallons is appropriate for a single field mouse or a pair of females. Ensure the enclosure is secure and escape-proof, as field mice are agile climbers and escape artists.
For bedding, use aspen shavings or paper-based bedding. Avoid cedar or pine shavings, as these can release harmful aromatic oils that are toxic to rodents. Provide a thick layer of bedding to allow for burrowing, a natural behavior for field mice.
Food and Water: Essential Provisions
In the wild, field mice have a varied diet consisting of seeds, nuts, fruits, insects, and occasionally small invertebrates. In captivity, you can provide a high-quality rodent food mix as a staple diet. Supplement this with small amounts of fresh vegetables, fruits, and seeds. Treats like peanut butter (in moderation) and small pieces of cheese can also be offered, but should not be given excessively.
Fresh, clean water should always be available. The best way to provide water is through a sipper bottle, which prevents contamination and keeps the water clean.
Enrichment and Exercise: Keeping Them Active
Field mice are active creatures and need opportunities for exercise and mental stimulation. An exercise wheel is essential for them to run and burn energy. Provide toys such as cardboard tubes, wooden chew toys, and ladders to encourage climbing and exploration. Cluttering the cage with safe, enriching items mimics their natural environment and reduces boredom and stress.
Caring for Your Field Mouse Pet
Caring for a field mouse goes beyond just providing food and shelter. It involves understanding their specific needs and behaviors.
Handling and Bonding: Building Trust
Initially, your field mouse will likely be fearful and skittish. Gentle and patient handling is crucial for building trust. Start by talking softly to the mouse near its cage to get it used to your voice. Offer treats from your hand to encourage interaction. Avoid sudden movements or loud noises that could frighten it.
Once the mouse seems more comfortable, you can attempt to handle it. Cup your hands gently and allow the mouse to crawl into them. Keep handling sessions short and positive, and never force interaction. Remember, field mice are not naturally cuddly pets like domesticated mice and may never fully enjoy handling.
Diet and Nutrition: What to Feed Your Wild Pet
While they will eat commercial rodent food, supplementing their diet with variety is important for their health and well-being. Offer small amounts of:
- Seeds and nuts: Sunflower seeds, pumpkin seeds, millet, and unsalted nuts.
- Fresh vegetables: Carrots, broccoli, leafy greens (in moderation).
- Fruits: Berries, small pieces of apple (avoid citrus fruits).
- Insects: Mealworms or crickets (occasionally as a treat).
Avoid sugary treats, processed foods, and anything high in fat. Always research if a particular food is safe for mice before offering it.
Health and Lifespan: Keeping Your Mouse Healthy
Field mice in the wild typically live shorter lives due to predation and environmental challenges. However, in a safe and nurturing captive environment, they can live for 2-3 years, and sometimes even longer.
Regularly clean the cage to maintain hygiene and prevent disease. Monitor your mouse for any signs of illness, such as lethargy, loss of appetite, sneezing, or discharge from eyes or nose. Finding a veterinarian experienced with exotic pets or rodents is advisable in case of health issues.
Potential Challenges and Considerations
Keeping a field mouse as a pet is not without its challenges.
Wild Nature and Taming Limitations
Even if captured young, a field mouse will retain many of its wild instincts. They are not as easily tamed as domesticated pet mice and may always be somewhat skittish and less interactive. Lower your expectations for cuddly companionship.
Disease Risks and Hygiene
Wild animals can carry diseases and parasites. While the risk is generally low with field mice, practicing good hygiene is essential. Always wash your hands thoroughly after handling your mouse or cleaning its cage. Be aware of potential zoonotic diseases, though the risk is minimal with proper care.
Escape Artists and Housing Security
Field mice are incredibly adept at escaping enclosures. You must ensure the cage is absolutely secure and that there are no gaps or weak points. Regularly inspect the cage for any signs of damage or potential escape routes.
Conclusion: Is a Field Mouse the Right Pet for You?
Keeping a field mouse as a pet is a unique and potentially rewarding experience for dedicated and informed individuals. However, it’s crucial to weigh the ethical, legal, and practical considerations carefully. Field mice are not domesticated animals and require specialized care and understanding.
If you are prepared to provide a spacious, enriching environment, are patient and understanding of their wild nature, and are committed to responsible pet ownership, then keeping a field mouse might be an interesting path to explore. However, for many, the ethical concerns and challenges of taming a wild animal might outweigh the appeal. Consider adopting a domesticated pet mouse from a reputable breeder or rescue organization instead, if you’re looking for a more traditional and easily manageable pet rodent. Ultimately, the decision of whether or not to keep a field mouse as a pet should be made with the well-being of the animal as the top priority.
