Cats and Cat Years Conversion

Converting between cat years and human years isn't as simple as using a factor of 7 (as some people erroneously think with dogs, and sometimes cats). The main reason is that cats mature quickly in the first couple of years of life. To convert cat age to an equivalent human age, an accepted method is to add 15 years for the first year of life. Then add 10 years for the second year of life. After that, add 4 years for every cat year. This means that by year two, a cat has matured to about the same as a 25 year old human.

So it isn't terribly complex, but you would have to do some figuring on paper or in your head. That's where the cat years calculator below comes in handy, which uses the above formula.

Not everyone agrees on the same conversion formula. For a slightly different calculation, the Cat Bible, a book by Tracie Hotchner, provides the following list:

  • 1-month-old kitten = 6-month-old human baby
  • 3-month-old kitten = 4-year-old child
  • 6-month-old kitten = 10 human years old
  • 8-month-old kitten = 15-year-old human
  • A 1-year-old cat has reached adulthood, the equivalent of 18 human years
  • 2 human years = 24 cat years
  • 4 human years = 35 cat years
  • 6 human years = 42 cat years
  • 8 human years = 50 cat years
  • 10 human years = 60 cat years
  • 12 human years = 70 cat years
  • 14 human years = 80 cat years
  • 16 human years = 84 cat years
Because you can look at the conversion in two different ways, it can be somewhat confusing.
  1. First Perspective: If we assume the maximum age of a human is 100 years old and put that into the calculator formula below, it indicates the equivalent age of a cat (that is, the assumed maximum age of a cat) is 20.8 years. So if you are 100, we can say you are "20.8 cat years old".
  2. Second Perspective is like the Cat Bible above, which says if your age is, for example 16 years, then your cat is nearing the end of its life and is like a human that is 84 years old, so we can say you are "84 cat years old" or for comparison with the first perspective, if your age is 100 years you would be roughly "500 cat years old".


I THOUGHT THIS AGE THING ONLY PERTAINED TO DOGS--HOW OLD ARE YOUR CATS IN HUMAN YEARS???:bookworm::nailbiting:

They will always be my babies, no matter how old they really are.
Wiggley is 24
Cleo is 24
Pinky is 35.
Muffy is 85! She's a grandma!

It's hard to believe because , Wiggley acts like a typical 2 yr toddler. Like I said, they will always be babies to me.

Hmm, Cleopatra and Monita are about 55 years old and they act like two old birds, too old for playing, so it seems about right. Rosie is the baby, 15 years and Poppy is around 16 and a half. But like the others, they are all baby girls to me- I still call out "BABIES!" at dinner time and have them all come running!
