Cats age faster when they're younger, but this slows down as they get older. At 6 months of age, a female cat already can reproduce. At 1 year of age, cat bones fully stop growing. This occurs in people at approximately 24 years of age, give or take a few years. So, a 1-year-old cat is roughly equivalent to a 24-year-old person. From that point on, cats age approximately four years for every one year. While this is certainly not an exact science, the table below should offer a reasonable guideline as to how cats age compared to humans.

Cat Age Human Age

6 months 15 years

1 year 24 years

2 years 28 years

3 years 32 years

4 years 36 years

5 years 40 years

6 years 44 years

7 years 48 years

8 years 52 years

9 years 56 years

10 years 60 years

11 years 64 years

12 years 68 years

13 years 72 years

14 years 76 years

15 years 80 years

16 years 84 years

17 years 88 years

18 years 92 years

19 years 96 years

20 years 100 years

Is there a difference between dog and cat years?

Yes, there's a difference between cat years and dog years. What we call "dog years"(to calculate a dog's "human" age), is simple. For every human year a dog has lived, that's 7 "dog years". So a 2 year old dog is 14 dog years, while a 5 year old dog is 35 dog years. A cat's age is a little more tricky. Different sources vary slightly, but this is the most common way. The first year of a cat's life is 15 "cat years". Then you add 9 "cat years" for the second year, so a 2 "human year" old cat is 24 "cat years". For every "human year" after that, you add 4 "cat years". An 8 "human year" old cat would be 48 "cat years". "human year" = 365 days, one revolution around the Sun "cat year" = the comparative "year" for a cat based on milestones, such as walking, sexual maturity


I am twenty nine what age imy cat he is 11 yers old now?

# Allow 15 human years for the first year of your cat's life. # Add nine years for the second year. A two-year old cat will approximate 24 human years. # Add four human years each for successive years of his life. so your cat is 60 years old.


How old is a 3 year-old cat in human years?

A 3 year-old cat is roughly equivalent to a 28-30 year-old human in terms of aging. This is based on the common guideline that each cat year is roughly equivalent to 4-6 human years, with variations depending on factors like breed and overall health.

How old would cats be in 100 in cat year?

The cat would be 20 in human years, although I've never heard of a cat living that long. The oldest cat I've ever heard of (and met) was 16 (human years).

How old is a cat in 1 human year?

First allow 15 human years for the 1st year of your cat's life, then add 9 years for the 2nd. Add 4 years each year from the third year on out. For example: 1 cat year = 15 human years, 2 cat years= 24 human years, 3 cat years = 28 human years, and 4 cat years = 32 human years and so on.

If your cats seven how old is she in cat years?

Do NOT use the dog years formula. Cats age more quickly in the first years of their lives. The first year of a cats life is about fifteen years. the second year is about ten. so by the time a cat is two, it will have reached adulthood. Every year following is about 4 years. Example: 5 human years = 37 cat years Not 35 cat years (the dog years formula)


What is the ratio between the age of a cat and the age of a person e.g. is a 3-year-old cat the equivalent of a 21-year-old person?

A common rule of thumb is that one cat year is roughly equivalent to 4 human years for the first two years of a cat's life, then each additional year is roughly equivalent to 2-3 human years, depending on the cat's breed and overall health. So a 3-year-old cat would be roughly equivalent to a human age of around 28-32 years.


If you cat is 1 in human years how old is it in cat years?

Your cat should be around 60 cat years old in human years. Aging occurs much faster during the first 2 years of a cat's life. By the age of 2, a cat will be around 24 years old in human terms. After the first 2 years, a cat will age approximately 4 cat years for every human year. If your cat is 11 years old now, it should be around 60 cat years old.


How many cat years is it in 1 years?

It is believed that to find a cats age you times the number of human years by 4. This is just something I have heard and that others have told me. So if this is the case your cat is 4 years old.


How old is a 16 year old cat in human years?

42, one cat year is considered equal to 7 human years. No it's 54. 7 years is with dogs, for cats it's 9. Easy to remember because they say a cat has nine lives. Source: the cats veterinarian.
