How long will a pet mouse live with proper care?

With proper care, a pet mouse can live for 18 to 30 months, or even longer in some cases.

However, their lifespan can be influenced by several factors:

* Breed: Some breeds, like the fancy mice, tend to live a little longer than others.

* Diet: A balanced and nutritious diet is crucial for a long and healthy life.

* Environment: A clean, spacious cage with proper enrichment and temperature control can significantly impact their lifespan.

* Genetics: Just like humans, some mice are genetically predisposed to certain health issues that can shorten their lifespan.

It's important to note that these are just estimates. Some mice may live shorter or longer lives depending on individual factors.
