Cat Age Calculator

Cats mature much earlier than humans and after one year they are fully developed and have reached sexual maturity. The kittenhood of a cat is very short when compared to the childhood of humans. The first two years of a cat's life are when the relative age difference between humans and cats is the greatest, as this includes both kittenhood (childhood) and young adulthood (teenager).

Using the form below you can compare your cat's age to relative human years. Remember that this conversion is only an approximation;
but it is a useful tool to help you understand the physiological changes which your cat undergoes as he ages.
