How the Cat Age Calculator Works
The old "multiply by 7" rule doesn't apply to cats. Cats mature much faster in their first two years:
- •First year: A 1-year-old cat is roughly 15 in human years
- •Second year: Adds another 9 human years (total 24)
- •After age 2: Each cat year equals about 4 human years
Frequently Asked Questions

Indoor cats typically live 12-18 years, with some reaching their early 20s. Outdoor cats have shorter lifespans averaging 5-10 years due to hazards.
At what age is a cat considered senior?
Cats are generally considered senior around 11 years old, and geriatric at 15+. However, many cats remain active and healthy well into their senior years.
Do indoor cats age differently than outdoor cats?
Indoor cats tend to live longer due to reduced exposure to hazards, diseases, and predators. The aging process is similar, but outdoor cats may show more wear.
