Ferrets tend to live to be around six to ten years old, although they can survive for much longer, with some of the oldest domestic ferrets living to around 15 years old.
My ferret personally lived to be 14 years old and he was the best thing ever. depending on how much love you give it can really be a factor in its life span.
Pet ferrets have a life expectancy of 7-9 years. There are some illnesses and conditions to watch out for, though so get them a check up to maximize their lifespan.
Ferrets generally have a natural life span of between five and seven years. However domesticated ones which receive excellent care can have their life significantly extended, some living up to ten years.
