How Cat Age Calculation Works

Cats mature rapidly in their first few years. Forget the old "multiply by 7" myth — here's the accurate way to understand your cat's age in human years.

  • 1 Cat Year = 15 Human Years
  • 2 Cat Years = 24 Human Years
  • Each Year After = +4 Human Years

Formula:
Human Age = (Cat Age − 2) × 4 + 24
