🐈 Cat Age Calculator
Calculate your cat's age in human years using veterinary-backed formulas from AAFP guidelines
How This Works
This calculator uses age conversion guidelines from the American Association of Feline Practitioners (AAFP) and American Animal Hospital Association. Cats age rapidly in their first two years, then more gradually afterward.
- First year: approximately 15 human years
- Second year: approximately 9 human years (total 24)
- Each year after: approximately 4 human years
Average Life Expectancy
Indoor cats typically live 12-18 years (average 15 years), while outdoor cats have a much shorter lifespan of 2-5 years due to increased risks.
