How old is a one-year-old cat in human years?

A one-year-old cat is commonly compared with a 15-year-old human.

How old is a two-year-old cat in human years?

A two-year-old cat is approximately 24 human years old. After that, each cat year adds about four human years.

Can I calculate the age of a kitten in months?

Yes. Select the known-age option and enter zero years plus the number of completed months.

Does indoor or outdoor lifestyle change the conversion?

No. Lifestyle does not change the age formula; it is included only to make the profile and care discussion more relevant.
