Cat Age Calculator

You can calculate the age of your cat, in human years, as well as your age in cat years with the Cat Age Calculator. Cats develop particularly quickly in the first few years of their life and then more slowly once they reach maturity. The first year of a cat´s life is equivalent to 15 human years whilst the second year is only equivalent to 10 human years. When a cat has fully grown into an adult, each cat year is equivalent to 4 human years.
