Cat years

The life expectancy of a cat is typically 12–15 years. However, some cats may attain the age of 21 years or more.^[1] By comparison, the average life expectancy of humans in the United States at birth in 2014 was 79.56 years.^[2] A one-year-old cat is roughly comparable, in developmental terms, to a 15-year-old-human. Subsequent years of a cat's life add progressively fewer years to its human age equivalent, so that a 15-year-old cat is roughly comparable, developmentally, to a 76-year-old human.^[3]

The table below shows the correspondence between a cat's chronological age and the age of a human at a comparable stage of development.
