Cat Age Calculator
Cats mature especially quickly in their first two years. Enter your cat's age to see an approximate human-age comparison and feline life stage.
How cat age compares
The age conversion follows published feline age charts: about 15 human years at age 1, about 24 at age 2, then roughly four human years for each additional cat year.
Feline life stages
This tool uses the 2021 AAHA/AAFP framework: kitten, young adult, mature adult and senior. Life-stage boundaries are guides, not absolute biological cutoffs.
