Can You Keep A Mouse As A Pet? Absolutely! While it may initially seem like a good idea, it’s important to note the key differences between domestically bred mice and house mice. At pets.edu.vn, we understand the allure of these tiny creatures and offer guidance to help you make the best decision for you and the mouse. Whether you’re considering a wild mouse or a fancy mouse, understanding their needs ensures a happy, healthy life together. Dive in to discover the essentials of mouse care, fancy mice, rodent care, and safe pet practices.
1. House Mice Are Not Pets
Alt text: A wild house mouse scurries along a concrete sidewalk.
A house mouse is a small rodent recognized by its pointed snout, rounded ears, and a hairless tail. While their color can vary, they generally come in agouti, where a single hair displays different colors. In sunlight, a house mouse may appear brown with fine streaks of black, white, or gray.
Both wild house mice and fancy mice belong to the same species. However, domesticated mice are specifically bred for handling and companionship, making them suitable pets. In contrast, a feral house mouse primarily focuses on survival, displaying a reluctance to be handled and a tendency to escape if caged.
Another significant consideration is that house mice can carry diseases that fancy mice might not. For instance, a single house mouse could carry tapeworms, which can spread to other animals in the household. They can also carry and spread Hantavirus, a family of life-threatening diseases.
2. Think Twice About Keeping a House Mouse
Alt text: A house mouse peers out from inside a humane trap.
There’s nothing legally stopping you from keeping a house mouse as a pet. Yet, here is some information that could help you make a well-informed decision:
- Wild mice carry diseases. According to the Centers for Disease Control and Prevention (CDC), wild mice can spread salmonella, typhus, and even the plague. While house mice rarely carry rabies, you don’t want to risk any threats to your health—or that of other rodents you keep.
- House mice may stress in cages. A house mouse generally forages and lives within 30 feet of its nest. It may seem like a small radius, but for a small rodent, it’s generous. Being in a cage could cause stress, aggression, and premature death.
- Mice shouldn’t live alone. Mice can live in colonies with up to 24 members. They are social creatures that thrive on interaction with others. Keeping a house mouse by itself is cruel. It might also not take kindly to other, unfamiliar mice, leading to fights.
By purchasing a well-bred fancy mouse from a reputable breeder, you avoid these risks. These pets are screened for diseases, socialized from a young age, and specifically bred for animal husbandry.
3. What if I Want to Rescue a House Mouse?
Alt text: A trio of black fancy mice explore their enclosure.
If you capture a house mouse, it’s best practice to keep it in a secure container and release it at least two miles away from your home. Mice are remarkably intelligent and can find their way back to their nests if relocated too closely. This ensures you don’t end up catching the same mouse repeatedly.
However, if the mouse is injured or appears ill, the situation changes. In such cases, contacting your local wildlife rehabilitation organization is the best course of action. These organizations have trained staff who can provide the necessary nutrition, medications, and other therapies the animal needs.
Mice have relatively weak immune systems, and because they cannot vomit, ingesting poison is often fatal. If the mouse is beyond help, a rescue organization can offer humane euthanasia, ensuring a peaceful end. According to the Humane Society, euthanasia should be performed by trained professionals to minimize suffering.
4. Beware of “Docile” House Mice
Alt text: A close-up of a wild house mouse showing its detailed features.
House mice are prey animals—and they are keenly aware of it. When confronted with a threat (or a perceived one), their natural instinct is to scurry away and seek shelter. Occasionally, however, you may encounter a house mouse that doesn’t seem to mind being handled, readily accepts food, and even sits calmly in the palm of your hand. While this might seem like an ideal pet, it’s crucial to think twice.
Mice that are diseased may lack the energy to fend for themselves or escape a precarious situation. Ingesting poison can cause neurological problems, leading to confusion or disorientation. Handling a wild, potentially sick animal can pose risks to your health, regardless of how cute or friendly it may appear. The World Health Organization (WHO) emphasizes the importance of avoiding contact with wild animals to prevent the spread of zoonotic diseases.
As noted, the most responsible course of action for a captured house mouse is to relocate it away from your home or bring it to a reputable rescue organization. The perceived benefits of keeping it as a pet could quickly be overshadowed by unforeseen challenges.
5. What You Need for Keeping Pet Mice
Alt text: A suitable cage setup for pet mice, including bedding, water bottle, and enrichment items.
At most pet stores, mouse enclosures are typically small to medium-sized cages with colorful, plastic tubing. While visually appealing, these often fall short of meeting the needs of a mouse nest and can be easily broken through, leading to escapes.
If you plan on keeping two to three mice, a cage that’s 18 inches long, 18 inches wide, and 10 inches tall is recommended, according to the Merck Veterinary Manual. A water bottle with a hanger ensures consistent hydration, and a few inches of wood shavings or prepared litter provide burrowing opportunities.
Commercial mice diets contain all the necessary vitamins and minerals for a healthy life. Supplementing their diet with sunflower seeds and fruit can add variety. Unlike rats, mice don’t require constant one-on-one attention. They thrive with a running wheel, climbing blocks, and ladders.
