* Genetics: Some breeds are naturally more prone to certain health problems.
* Diet: A nutritious and balanced diet can significantly extend a fancy mouse's lifespan.
* Environment: A clean, spacious cage with proper enrichment and temperature control can improve their health and longevity.
* Care: Regular vet checkups, prompt treatment for illnesses, and proper handling can all contribute to a longer lifespan.
Generally, fancy mice have an average lifespan of 18-30 months (1.5-2.5 years).
However, some mice may live longer, reaching 3-4 years with excellent care.
Here's a breakdown of some factors that affect lifespan:
* Dwarf mice: These tend to have shorter lifespans, typically around 18-24 months.
* Roborovski hamsters: These are the smallest hamster species and can live for up to 3 years.
* Syrian hamsters: These are larger and can live for up to 2-3 years.
* Russian dwarf hamsters: These are smaller than Syrian hamsters and can live for up to 2 years.
It's important to remember that each mouse is an individual, and their lifespan can vary significantly.
