Pet mice are popular small animals that are often kept as companions. But how long do they live? The average lifespan of a pet mouse is about 1 to 2 years, though some mice may live up to 3 years with proper care. However, there are a number of factors that can affect a mouse's lifespan, including its diet, exercise, and overall health.

How Long Does a Pet Mouse Live?

Factors That Affect a Mouse's Lifespan

1. Diet: A healthy diet is essential for a long and healthy life for any pet, and mice are no exception. Mice should be fed a diet that is high in quality hay, fresh vegetables, and a small amount of high-quality pellets. Avoid feeding your mouse sugary treats or processed foods, as these can contribute to health problems and a shorter lifespan.

2. Exercise: Mice are active animals and need plenty of opportunities to run, climb, and explore. Providing your mouse with a large cage with plenty of toys and hiding places will help keep it active and entertained. A bored mouse is more likely to develop health problems, which can shorten its lifespan.

3. Overall Health: Of course, a mouse's overall health also plays a role in its lifespan. Mice that are healthy and free from disease are more likely to live longer lives. Regular veterinary checkups can help identify and treat any health problems early on, helping to extend your mouse's lifespan.

Signs of Aging in Mice

As mice age, they may start to show signs of aging, such as:

1. Decreased activity

2. Loss of appetite and weight

3. Increased sleeping

4. Difficulty grooming

5. Changes in coat condition

If you notice any of these signs in your mouse, it's important to take it to the vet to rule out any underlying health problems.
