How long does a long tailed weasel live?

Many long-tailed weasels die before reaching one year old. However, once they have reached adulthood they may live for several years. The lifespan of long-tailed weasels in the wild is not well known. http://animaldiversity.ummz.umich.edu/site/accounts/information/Mustela_frenata.html My weasel lived for 11 & a half years.But my cousins ferret lived for 3 years
