Yes. A cat that is 15 years old would be around 80 years old in human years. Some cats live to be 17 or 18 years old (85 to 90 in human years), or even longer. I think the Guinness World Record for longest-living cat was 25 years (something like that).

You mean cat years. 153 yrs *the oldest cat ever was 34 yrs
I'd say no. It has never been done before. Cats normally live to be 9-15. If a cat were 100 in human years than in cat years they would be about 420 years old, which is not even possible for a human.
The cat would be 20 in human years, although I've never heard of a cat living that long. The oldest cat I've ever heard of (and met) was 16 (human years).
A cat is considered a senior at 7+ years of age.
# Allow 15 human years for the first year of your cat's life. # Add nine years for the second year. A two-year old cat will approximate 24 human years. # Add four human years each for successive years of his life. Your cat is 56 in cat years. My childhood cat lived to be 19 years old; that's 92 in cat years! Source: http://cats.about.com/cs/catmanagement101/ht/convertcatyears.htm

40. It is believed that for every human year a cat year is 5.
A common formula to estimate cat years is to count the first two years as 24 human years, and then add 4 human years for each additional cat year. So, when the cat turns 17 in human years, he would be approximately 84 in cat years.
Cats can live to be very old, as much as 15 years in human years. They say that at cat that has lived outside can live longer than an exclusivly inside cat.
A 21 year old cat is about 101 years old in human years.
