How cat years compare to human years
The American Animal Hospital Association (AAHA) and American Association of Feline Practitioners (AAFP) life-stage guidelines line cats up with people like this: kitten (0–1), young adult (1–6), mature adult (7–10) and senior (10+). The common conversion is 15 human years for the first year, 9 for the second and about 4 for each year after.
