Aging in cats

To date, reliable information on the lifespans of domestic cats is varied and relatively scant.[1] Nevertheless, a number of studies have investigated the matter and have come up with noteworthy estimates. Estimates of mean lifespan in these studies range between 13 and 17 years, with a single value in the neighbourhood of 15 years.[2][3][4] At least one study found a median lifespan value of 14 years and a corresponding interquartile range of 9 to 17 years.[5] Maximum lifespan has been estimated at values ranging from 22 to 30 years although there have been unverified claims of cats dying at ages greater than 30 years.[1][2][5][6][7][8] Female cats have been evidenced to outlive male cats, while neutered cats and crossbred cats have been evidenced to outlive entire and purebred cats, respectively.[2][5] It has also been found that the greater a cat's weight, the lower its life expectancy on average.[5]

The life expectancy of a cat that is living indoors is typically 15.1 years.[9] In one study of cat mortality, the most frequent causes were trauma (12.2%), renal disorder (12.1%), non-specific illness (11.2%), neoplasia (10.8%) and mass lesion disorders (10.2%).[5]

The oldest cat ever recorded was Creme Puff, who died in 2005, aged 38 years, 3 days.[10]
