Quick Answer
Use the calculator below to find your ferret's age in human years. The old "multiply by 7" rule is inaccurate — aging varies by size and breed.
How Old Is My Ferret in Human Years?
Ferrets live 5-8 years on average, aging much faster than dogs or cats. They are considered senior by age 4 and are prone to adrenal disease as they age.
With proper care, many ferrets exceed this average.

💚 How to Help Your Ferret Live Longer
High-Quality Diet
Ferrets are obligate carnivores. Feed high-protein, high-fat kibble or raw diet.

Regular Vet Checkups
Biannual exams after age 3. Blood glucose monitoring for insulinoma.
Mental Stimulation
Tunnels, toys, and daily out-of-cage playtime prevent depression.
