How Do Cat Years Work: How Old is My Cat?

How do cat years compare to human years, and how can we calculate exactly how old our cats are? We’re taking a look at how cat years work, to help you find out more about your cat’s age. There’s even a handy table below so you can find out exactly how old your cat is in cat years!

What is a cat year?

Cat years allow us to calculate a cat’s age to an equivalent human age. On average, cats live to around 12-14 years of age—although they can live much longer! One cat year is equivalent to multiple human years, but not all cat years are created equal...


How do cat years work?

The comparison between cat years and human years changes as cats grow up.

Because cats mature so much in the first year of their life, this first year is equivalent to 15 human years. 

As they continue to mature into adolescence and adulthood, their second year equals around 9 human years.

This means that a two year old cat is roughly 24 years old in human years!

Once cats reach their third year, it’s approximately four human years, and it carries on like this for the rest of their life.

How old is my cat?


Human Years Cat Years
1 year 15 cat years
2 years 24 cat years
3 years 28 cat years
4 years 32 cat years
5 years 36 cat years
6 years 40 cat years
7 years 44 cat years
8 years 48 cat years
9 years 52 cat years
10 years 56 cat years
11 years 60 cat years
12 years 64 cat years
13 years 68 cat years
14 years 72 cat years
15 years 76 cat years


And then continue to add 4 years for every additional year!

Some cats can live to be around 20 years old, which would make them an impressive 96 in cat years. 

The oldest cat ever recorded was Creme Puff, who lived to be an amazing 38 years of age.

The current record holder for the oldest living cat is Flossie, who is 27 years old and lives in the UK!
