Cat age in human years
Cats age quickly in the first two years — about 15 human years by age 1 and 24 by age 2. After that, many reference charts add about four human years for each additional cat year.
Individual cats vary by breed, indoor/outdoor lifestyle, and health. This chart is a population reference, not a clinical life-stage assessment.
Example: a 7-year-old cat ≈ 44 human years (24 + 5×4). A 12-year-old cat ≈ 64 human years.

Common questions
Do indoor cats live longer?
Indoor cats often avoid outdoor hazards, but lifespan depends on genetics, diet, and veterinary care — not this chart alone.
Is this the same as AAHA dog charts?
No. Feline charts use a different progression. This tool follows a common AAFP-style reference.
