About Cat Age Conversion

The traditional notion that one cat year equals seven human years is inaccurate. Cats mature much more rapidly in their first two years of life compared to humans.

Cat Age Development

A more accurate conversion considers that:

  • A 1-year-old cat is developmentally equivalent to a 15-year-old human
  • A 2-year-old cat is developmentally equivalent to a 24-year-old human
  • After 2 years, each additional cat year equals approximately 4 human years
Indoor vs. Outdoor Cats

Indoor cats typically live longer than outdoor cats due to reduced exposure to hazards, disease, and predators. This calculator adjusts the age conversion based on your cat's lifestyle:

  • Indoor cats have a longer life expectancy of 12-18 years on average
  • Outdoor cats have a shorter life expectancy of 5-7 years on average
  • Mixed indoor/outdoor cats fall somewhere in between
