Thread Name: BS: Life Expectancy in Cats
Subject: RE: BS: Life Expectancy in Cats
There's no realistic linear relationship between cat years and human years, but one
formula for cat years is based on a cat reaching maturity in approximately 1 year, which could be seen as 16 in human terms, then adding about 4 years for every year the cat ages. A 5-year-old cat would then be (5 − 1) 4 + 16 = 32 "cat years" (i.e. human-equivalent years), and a 10-year-old cat (10 − 1) 4 + 16 = 52 in human terms.
At any rate, indoor cats have been known to live into their twenties and even indoor-outdoor cats can live into their late teens.
