Cats and cat years
Conversion between cat years and human years is not as easy as walking by 7 (as some people mistakenly believe in dogs, and sometimes cats). The main reason is that cats grow rapidly in the first couple of years of life. To convert the age of the cat to a corresponding human age, an accepted method is 15 years in the first year of life. Then add 10 years for the second year of life. After that, add four years for each year. This means that by year two, a cat has become about as old as a 25 year old man.
So it's not very complicated, but some headlines are being cleaned to find out your cat's age. That's where this cat's calculator comes handy.
