Today cats live longer than ever. Just 20 years ago the life expectancy of a cat was four to six years; today they live 15 years or more. Life expectancy in cats depends on many things, but the most important factor is whether he is an indoor-only cat or an outdoor cat.

Cats have been known to live to 20 years or more, but it really depends on the health of the cat and how well it is taken care of.
