How Old is Your Cat in Human Years?

What a cat’s age is equal to in human years…

The Traveling Cats

There are some calculators and formula you can find online and use to convert a cat’s age to its equivalent in human years so to speak.

According to Calculator Cat, the first year is equivalent to 15 years. On the cat’s second birthday, add 10 years. Then add 4 years for every birthday that follows.

What this is saying is that when a cat is two years old, she/he has matured to about the same as a 25 year old human.

Let us find out how old our furry babies are in the de Block household.

Here are our eight cats’ actual ages or estimated in the case of their mother, Lucky.

Mama Lucky – was about a year old or younger when we adopted her in July 2011 (1 + 4.17 = about 5 years or a bit younger)
Aiko – was born with Oue around mid-November of 2011 (2 mos short of 4 years)
Oue – was born with Aiko around mid-November of 2011 (2 mos short of 4 years)
Umeko – was born on March 21, 2012 (3.5 years)
Splash – was born on March 21, 2012 (3.5 years)
Cotton – was born on March 21, 2012 (3.5 years)
Snoozie – was born on March 21, 2012 (3.5 years)
Dancer – was born on March 21, 2012 (3.5 years)

Let’s get their “human ages” using this Calculator…

Their “human years/ages”:

Mama Lucky – about 37 years old Oh Mama Lucky you seem to be old enough to be my big sister! 🙂
Aiko – 32.3 years old
Oue – 32.3 years old
Umeko – 31 years old
Splash – 31 years old
Cotton – 31 years old
Snoozie – 31 years old
Dancer – 31 years old

This is saying that all the furry balls in our house are in their 30s. We are about age-mates! 🙂

So just for fun, how old is your cat in so-called human years?
