When they ask us about the age of cats in relation to humans and we answer, many times we are not able to extrapolate this data to the relationship between a cat and a man.

We all think that a year for humans equals 7 for cats, but recent studies on the subject are changing that parity in part, because domestic cats live longer.

How old are cats for a person?

The lifespan of cats relative to humans can be expected to continue to increase, provided the animals receive veterinary attention, care from their owners, and an appropriate diet.

The basic relation we can apply is the following:

* A two-year-old cat equals a 21-year-old human.

* From the age of two, every year a cat increases, they are the equivalent of four humans.

Have you ever wondered how old your cat is in human years? One way to calculate their age is to use the general rule that a 5-year-old cat is equivalent to a 33-year-old human. To determine this, we can add the 21 human years for the first two years of a cat’s life, and then add the remaining three years of the cat, which gives us a total of 12 human years. So, 21 years plus 12 years equals 33 human years for a 5-year-old cat.
