A 13 year old cat in cat years is 13 years old... in human years 68 years old.
A 21 year old cat is about 101 years old in human years.
If the cat is 13 years and 2 months in 'regular', human, years, then in cat years, how old it really is in their world, it is about 72 years. If it is 13 years in 2 months in cat years, if you go backwards (or at least backwards from our point of view) the cat is only 6 months old. I say all this because usually people ask this type of question like, "How old is your 13 year old and 2 month old Persian cat in cat years?" because the vet told them they were that age and they want to find out how old they are in CAT years. Your question was a little confusing to me on which one you meant, so I put in both ways. :)
(s)he is 15 years old
72 cat years.

You multiply the age of your cat by seven. For example, if your cat is 2 years old, you would do 2x7 which is 14, so your cat's age in cat years is 14.
it's about 15 years old,but l'm not really sure
If a cat is 3 years-old. They are 29 years-old in human years.
In cat years, contrary to popular belief, the first year is 20 years and each year after that is 4 years. Therefore, the cat would be 24 cat years old.
around 41 to 56 years old
The lifetime of a cat can variate depending on not only living conditions, but breed as well. Accordingly, in average, a cat lives up to 17-20 years of age.
