Cat’s age calculation

There is no linear correspondence between cat age and human age. Cats usually grow at a faster rate than humans in the first two years, and then slow down. Here's a common way to calculate a cat's age, based on a widely accepted ratio:

The first two years: Each year is equivalent to 15 human years.

After the third year: each year is equivalent to 4 human years.
