What is the life expectancy of a calico cat?

The cat is female and she is spayed also she is an indoor cat.

same as any normal cat. I'd say 10-15 years.

When I was growing up I had a calico cat who lived to be almost twenty-years old.

mine lived 16 years

well a 'calico' cat is the same as any other cat, calico is the type of coloration it has, alot of people think its a breed, but its the tri-color it has. so a cat can live anywhere from 9-15, even 20 years...give and take a few years
