Mouse Lifespan: How Long Do Mice Live?

Mice are small rodents that are found on every continent except Antarctica. There are many different species, although one of the most common is the house mouse. Mice are often regarded as pests, especially if they find their way into homes or outbuildings. However, they’re also kept as pets. Whether you have a pet mouse or are just curious, you might be wondering how long they live. So, in this article, we’ll go over the lifespan of both pet mice and wild mice.

Pet Mouse Lifespan

The lifespan of mice differs depending on whether they are in the wild or kept as pets. The average lifespan of a pet mouse is typically between one and two years, although some may make it to three years or more with proper care and good genes.

What Are Typical Health Concerns For Pet Mice?

Mice are susceptible to respiratory infections and malignancies, but because of their small size, many mice can disguise their illnesses, making treatment difficult. Taking a sick pet to the vet is always a good idea, but mice owners should be aware that medical issues are often urgent and may necessitate euthanasia.

Pet mice commonly suffer from problems with their skin and hair. These issues can be caused by infections or infestations with mites, all of which can lead to hair loss and skin discomfort. Other issues that can occur with pet mice are respiratory infections, which can be caused by bacteria. Symptoms of a respiratory infection in mice include sneezing, a nasal discharge, lethargy, and difficulty breathing. If any of these symptoms occur then you should take your pet to a veterinarian immediately.

Can Owning A Pet Mouse Cause Health Problems In Humans?

Common house mice carry the LCM, or lymphocytic choriomeningitis organism. By inhaling dried airborne particles of the animal’s urine, feces, or saliva or eating food or dust contaminated by the rodent’s urine, people can become infected. Though it is quite unusual, LCM can affect the brain or the membranes that surround the brain and spinal cord. It primarily affects young adults.

Avoiding Illness

To avoid any illness in young pet owners, keep your youngster away from mice and hamsters, as well as their waste. Cages should be cleaned on a regular basis to avoid a deposit of dried excrement that could be blown into the air. Rat infestations should be prevented, especially in food storage facilities. Wipe the area with a liquid disinfectant if you find rodent droppings.

Wild Mouse Lifespan

Wild mice typically live for 12 to 18 months. However, this number can be shorter or longer, depending on the species and where they live. It’s possible for wild mice to live for two to three years if they take sanctuary in your home. The main factor affecting the lifespan of mice is the amount of predators they face. Common predators of mice include birds, snakes, foxes, and weasels. However, extreme temperatures, illness, and dehydration can also affect the lifespan of a mouse.

What To Do About Wild Mice In Your Home?

The only humane alternative for catching animals is to use live traps, which can be purchased at most hardware stores or online. Avoid poison at all costs as this can cause harmful effects on the ecosystem. Glue boards, snap traps, and other kill traps are not live traps.

If it is safe to do so, you can remove mice from your house and release them in a detached facility like a shed or garage. However, most house mice have a very slim chance of surviving in the wild after spending most of their lives in structures.
