Formula used to calculate the Cat Age Calculator

The common misconception that cat years are directly equivalent to human years (e.g., 1 cat year = 7 human years) is not accurate.

Cat age conversion to human age varies depending on the cat's life stages. The first two years of a cat's life have a much more rapid rate of maturation compared to later years. Here's a commonly used formula to estimate the conversion:

For the first two years of a cat's life:

For cat years beyond the second year:

This is a rough estimate and might not be exact for every cat. Cats can live well beyond 20 years, and the aging process might differ for individual cats.
