Calculate animal years to human years
Our calculator converts your pet's age to human years, helping you understand where your pet is in its life cycle. The conversion varies between species, as different animals age at very different rates.
Dog โ dog years to human years
The old rule of multiplying by 7 is inaccurate. In reality, dogs age very quickly in their first year, equivalent to about 15 human years. The second year equals about 9 human years, and then about 5 human years per dog year. Large breeds like Great Danes age faster than small breeds like Chihuahuas.
Cat โ cat years to human years
Cats also age quickly at first. The first cat year equals about 15 human years, the second about 9, and then about 4 human years per cat year. An indoor cat typically lives 12-18 years, while outdoor cats on average live shorter. A 10-year-old cat is equivalent to about 56 human years.
Rabbit โ rabbit years to human years
Rabbits age relatively fast. The first year equals about 21 human years, then about 8 human years per rabbit year. A rabbit typically lives 8-12 years depending on breed and care. Dwarf rabbits generally live longer than larger breeds.
Hamster โ hamster years to human years
Hamsters have a short lifespan of typically 2-3 years. They age very quickly โ the first year equals about 26 human years, and each subsequent year about 25 human years. A 2-year-old hamster is therefore equivalent to about 51 human years.
Why is the conversion important?
Understanding your pet's age in human years helps you adapt care, diet and exercise to the animal's life stage. An older animal has different needs than a young one โ just like humans. Regular vet visits are especially recommended for older pets.
