How it works
The first year counts as 15 human years and the second as 9 more. After that, each cat year adds 4 human years in this estimate.
Worked example
A cat that is 6 years old is about 40 in human years.
Questions
Is a cat year the same for every cat?
Not exactly. Breed, weight and care change the pace. This is an average, so treat it as a rough guide.
Does this show my cat's health?
No. It converts age only. For any health question, ask your vet.
Why do the first years count so much?
Kittens and young cats change very fast, so their first years cover more of a life stage than later years do.
