Full Answer

In order to survive in the wild, cats had to mature rapidly. A female cat can reproduce at six months, even before her bones stop growing. That's why veterinarians recommend spaying, and neutering, before a kitten reaches that age. After that two-year growth spurt, the age process settles down for the remainder of a cat's life.

One website, CalculatorCat.com, breaks the age comparison down even further. On the bottom left of the webpage is a Cat Years Calculator. By entering a cat's age in years, or months, it will calculate the human year equivalent. Change the entry from "My cat is" to "I am" and add a human age and the cat equivalent will appear.

The site also shows that the cat vs. human years comparison is not an exact science. A posted chart, taken from Tracie Hotchner's, "Cat Bible," notes that a one-year old cat is equivalent to an 18-year old human.
