Calculate the age of the cat in the human age
The calculation of the cat's age in human age is a natural tendency among cat owners.
The idea that you have to multiply the age of the cat by seven to have its equivalent in human age is an urban legend. It is actually very approximate.

Cats age much faster in their early years than they do in the second half of their lives. Knowing your cat's "human" age is always interesting to get an idea of the physical difficulties she may be experiencing: just compare her to a human.
The average life of a domestic cat
A domestic cat has an average life span of about 13 years. This figure doesn't speak volumes, as a cat's life expectancy varies greatly depending on its breed, its environment and the way it is cared for.
It is difficult, on the other hand, to have a cat that is over 16 years old: this is the case for only 18% of them.
That said, it is not a fatality, since the record of longevity was held by Puss, a cat that lived 36 years, which is exceptional! As a rule, if the cat is well cared for, pampered and fed, it has a life expectancy that is much higher than the average.
Correspondence between the age of cats and the age of humans
So that you can see more clearly the age of your cat, here is a table showing the correspondence, in number of years, of the age of cats with the age of men.
The real age of the cat | Human Age Equivalence |
1 year | 19 years old |
2 years | 24 years old |
3 years | 28 years of age |
4 years | 32 years old |
5 years | 36 years of age |
6 years of age | 40 years |
7 years old | 44 years of age |
8 years | 48 years of age |
9 years old | 52 years old |
10 years | 56 years of age |
Eleven years old | 60 years of age |
12 years old | 64 years of age |
13 years of age | 68 years of age |
14 years old | Seventy-two years |
15 years of age | 76 years old |
16 years of age | Eighty years |
Seventeen years old | 84 years old |
18 years of age | 88 years of age |
Nineteen years | 94 years old |
Twenty years | 100 years |
21 years of age | 110 years |
Hereditary factors
There are hereditary factors that explain why some cats have a lower than average life expectancy.
This is the case, for example, with certain hereditary conditions, such as polycystic kidney disease in Persian cats or hypertrophic cardiomyopathy in Maine Coons.
Reliable matches:
The coincidences between cat age and human age have been established after very precise calculations and veterinary observations made in cats.
The results are shown in the correspondence table. Thus, the cat acquires 19 "human" years at the end of its first year of life, then increases by 4 years in 4 years, then by 6 years in 6 years .
This is explained by the fact that the cat has a very fast growth, then stabilizes and ages less and less quickly.
