* Food availability: Mice with consistent access to food and water will live longer.
* Predation: Mice are prey for many animals, so living in a predator-free environment extends their lifespan.
* Disease: Infections and parasites can shorten their lifespan.
* Stress: Living in crowded or stressful conditions can negatively affect their health and longevity.
In controlled environments, like laboratories, house mice can live up to 3 years.
