House Mouse Age Chart

Many people love keeping mice as pets because of their small size, adorable appearance, and playful nature. If you are considering getting a mouse as a pet, it’s important to understand their lifespan and how they age. In this article, we will explore the house mouse age chart, which shows the different stages of a mouse’s life and what to expect at each age.

The House Mouse Age Chart Explained

The house mouse age chart is a helpful tool that allows mouse owners to track their pet’s growth and development. It provides information on the average lifespan of a mouse and the milestones they reach at different ages. By referring to the age chart, you can have a better understanding of your mouse’s needs and behaviors. Let’s dive into each stage of the house mouse age chart.

1. Newborn (0-2 days old)

Newborn mice are incredibly tiny and fragile. At this stage, they are completely dependent on their mother for nourishment and warmth. Their eyes and ears are closed, and their pink skin is sparsely covered with fine fur. They spend most of their time snuggled up with their littermates to stay warm.

2. Eyes Open (2-14 days old)

Around day 14, the mouse’s eyes start to open, allowing them to see the world around them for the first time. Their ears also begin to unfold, and they become more active, exploring their surroundings. However, they are still reliant on their mother’s milk for nourishment.

3. Weaning (14-28 days old)

Between two to four weeks of age, mice go through the weaning stage. They start transitioning from their mother’s milk to solid food. This is also the time when they become more playful and curious, venturing further away from the nest. It’s important to provide a balanced diet of fresh fruits, vegetables, seeds, and grains during this stage.

4. Adolescence (4-8 weeks old)

During this stage, mice continue to grow rapidly, both in size and maturity. They become sexually mature around 6-8 weeks of age, so it’s essential to separate males and females to prevent breeding. Mice at this age are full of energy and enjoy exploring their environment. Providing toys and a stimulating environment is crucial for their development.

5. Adulthood (8 weeks and older)

Once mice reach the age of 8 weeks, they are considered adults. At this stage, their growth rate slows down, and they reach their full size, which is about 2-4 inches in length. Males may become territorial and may fight for dominance, so it’s important to provide separate enclosures if you have multiple males. They usually live for about 1-2 years, although some mice can live up to 3 years with proper care.

What are some common health issues in mice?

Mice are prone to certain health issues, including respiratory infections, dental problems, and tumors.

If you notice any concerns, it’s best to consult a veterinarian who specializes in small animals.
