* Species: Different species of mice have different body sizes and predispositions to obesity.
* Diet: A diet high in fat and sugar will lead to more weight gain than a healthy diet.
* Genetics: Some mice are genetically predisposed to obesity.
* Activity level: A sedentary lifestyle can contribute to weight gain.
* Age: Older mice may gain weight due to slower metabolisms.
However, here are some general guidelines:

* Obesity: Mice can become obese and significantly exceed their average healthy weight. Some cases of obese mice can reach 50-70 grams or more.
* Health risks: Obesity in mice can lead to various health problems, including diabetes, heart disease, and joint problems.
It's important to remember:
* Monitor your pet mice's weight: If you notice your pet mouse gaining weight, it's essential to consult a veterinarian to discuss appropriate weight management strategies.
* Provide a healthy diet and exercise: Ensure your pet mouse has a balanced diet and enough space to exercise.
* Wild mice: Wild mice are more likely to have variable body weights depending on their environment and food availability.
If you're concerned about a mouse's weight, consulting a veterinarian is the best way to address the issue and ensure the animal's health.
