How to calculate the cat's human age?How old are cats?Is the equivalence that seven years in people equals one in the life of the cat true? Answering these questions will not only satisfy our curiosity, but it is also relevant to take care of our furry friend as he deserves. This article offers answer to all these questions, and collects different calculators of the cat's age in human years available on the internet.

How many human years do cats live?

Cats are longer today than a decade ago, and the number of felines that are over six years old has doubled

What would be the age of my cat if it were a human? Is the frequent equivalence that relates the seven years of a person to a year in the life of the cat true? Answering these questions not only allows us to fill our curiosity: knowing the correspondence between human years and feline age can also help us to better understand the needs of our four-legged friend, since their requirements - as occurs in people - vary with years.

So, How to calculate the cat's age in human years? The first obstacle to be saved is to know how old the current cats live, since, from there, we can begin the calculations.

"Like humans, we live longer today with respect to our ancestors, today's cats are also longer-lived," concludes a study on feline age conducted by Cornell University in the US.

In fact, the number of felines that exceed the six-year barrier has doubled in the last decade, explain these experts. Consequently, it is expected that the life expectancy of the feline will continue its upward trend, provided that the cats have veterinary care, care of their owners and appropriate feline feeding.

Cats live longer, but until what human age?

The life expectancy of a domestic cat ranges from 16 to 21 feline years

Not all cats are the same. And these feline divergences are significant, too, when it comes to calculating the age at which hairy friends enter their old age. Some cats begin to suffer the physical changes that warn of their arrival at the feline seniors between seven and twelve.

"However, other cats do not become elderly cats until age 12, so the equivalence that resembles people's seven years to one in feline age is not always accurate", add these scientists.

The question that should be answered as soon as possible then is: How long do current cats live? "The average life expectancy for a feline ranges between 16 and 21 years, although advances and veterinary treatments allow them to even overcome that barrier," collects, for its part, the publication 'Animal Research', a huge international base of scientific data on animal health.

Age records, however, also exist in this of feline brands. "Some cats can approach the barrier of 30 years of life, although in a very exceptional way," reports the scientific project 'The Human Genomic Resources', which collects data on aging and life expectancy of many of the animal species that We inhabit the planet Earth, including dogs and cats.

Calculate the age of the cat in human years

The increase in the average longevity of current cats explains, consequently, that the usual similarity of matching seven years of people to a feline year is not very precise. "Actually, a one year old cat could resemble a 16 year old human teenager", conclude Cornell scientists.

Since the rate of development is not constant in cats, the increase in their human years neither is it: in this way, "a two-year-old cat would be similar to a young 21-year-old human", they add. From that feline age, the equivalence would be as follows: every year that the cat meets, it would be as if a human turned four.

What do these calculations mean in feline longevity? This implies that a cat with ten years of age would be 53 years of age. To arrive at this calculation, it is necessary to operate in the following way: first, we must add to the 21 human years of the two-year-old feline, the remaining eight years of the cat, which are worth four humans. That is to say: 21 human years, plus 32 human years (to multiply eight times four), who have been in people for 53 years.

Similarly, we could estimate that a feline from 13 years will have turned 65 human years, while another of 15 could resemble an old man of 73 years.

Feline age calculators in human years

The formula explained above serves to calculate any age of the cat in its equivalence in human years. However, for the laziest or the least skilled with mathematics, the internet provides interesting feline age converters in human years

Although the equivalences are not always exactly the same as those found by scientists at Cornell University, the results are approximate and may be worthwhile.

These are some of the most interesting cat age calculators.

How long do cats live?

Life expectancy of cats depends on several factors. For starters, there is a big difference between the life expectancy of indoor cats and stray cats.

A typical domestic cat that lives safely inside can live between 12 and 15 years. On the other hand, it is likely that a stray or feral cat lives between 4 and 6 years in the wild.

What factors affect the longevity of cats?

As mentioned earlier, there are several factors that influence the life of each cat. We will review the crucial ones below.

The breed plays an intrinsic role in the longevity of a cat. Design and exotic breeds tend to have a shorter life expectancy than their more common counterparts. Sokoke, for example, is one of the felines with the lowest life expectancy.

Large domestic breeds, such as the American Shorthair, the Russian Blue and the Siamese, tend to live between 15 and 20 years. The life of the popular Abyssinian, a notoriously active and playful race, is 10 to 15 years.

Cat life

In order to get our best friend to live better and longer, we must comply with a series of care and controls. Domestic cats (as well as dogs) age faster than humans. That is why it is said, erroneously, that each year of man equals 7 years of a feline. Actually this is not so, but perhaps it can help us understand the cycle of your life.

Experts agree that cat aging is faster in its first two years. Thus, the changes that occur in the animal in its initial 24 months are superior to those experienced in the following years.

Generally the cat lives longer than the dog. But everything depends on care, food, race, if he lived on the street, if he was vaccinated, etc. A stray cat has a life expectancy of up to 6 years, and one who was always in a home can reach 12 years. There are even cases of cats that live 20 years.

Longevity then depends on the care the animal receives. Although their curious personality leads them to expose themselves to many dangers, the truth is that with a little vigilance and some limits we can avoid accidents that reduce their life expectancy.

Genetic heritage

Even if your spongy friend is the heir of pedigree parents of a famous and healthy lineage, the inheritance of DNA from their distant ancestors could make him prone to various diseases.

As they say "genetics is a lottery"


It is crucial to remember that nutrition is vital for any feline breed. High quality cat food is of intrinsic importance to your pet's longevity.

Specialized cat food meets the specific dietary requirements of felines, better overall cat health and helps your pet become a happy, prosperous and satisfied ball of hair.

General care

Cat food is not enough to ensure that your precious pet lives longer. Its general maintenance should never be neglected.

This means that you should not neglect the daily sessions of personal arrangement.

Brushing is very important especially for breeds with more hair loss.

Cats are cleaned, but it is not enough.

You have to keep your home clean, well ventilated and germ free because even indoor kittens can get allergies. And these allergies can severely shorten the life of your furry friend. Finally, baths and nail trimming are essential when it comes to feline maintenance.

3. Obesity

It is also something that reduces the life expectancy of your cat. Cats that don't go out much and don't exercise or play gain a lot of weight. And as with people, obesity has many dire consequences: heart attacks, clogged arteries, fluid retention, etc.


Countless reports show that sterilized females and neutered domestic cats tend to live longer. Why?

Sterilized cats do not get into heat, therefore, they are less likely to roam tirelessly, suffer from anxiety or frustration-induced depression, fight with other cats, contract pula and face other problems (such as dog attacks) While trying to find a partner.

In addition to all that, the procedure reduces the risks of ovarian and testicular cancer.

4. Lack of veterinary attention

Many pet owners do not take them to the consultation with the professional even once a year. With the excuse that "looks healthy", the cat does not receive medical attention and that can reduce their quality of life. Some diseases have no visible symptoms and when they are detected it may be too late.

How to know the age of a cat

If you don't know the exact age of your cat, there are some things that can help you guess it. Veterinarians often verify the following revealing aspects when determining the age of a feline: teeth, eyes, hair, skin and muscles.

A cat's teeth are very different from human teeth. Felines are carnivorous creatures. As such, their teeth are sharp and designed to cut meat instead of grinding food.

Kittens also use their teeth to groom themselves, so their pearly whites can easily wear out.

Older and older cats not only have stained incisors and molars, but also have tartar buildup. Lack of teeth, tooth decay, dark spots and gum disease are indicators of old age.

Apparently healthy teeth with little or no staining mean that the cat is about 1-2 years old.

Of course, if a pet's caretaker maintains the cat's dental hygiene, his teeth can fool him and make him think that the cat is much younger.

The excellent view of a cat is what makes these creatures such remarkable hunters. As with humans, feline vision worsens over time. Soft irises, bright and clear eyes, and little or no tearing / secretion are indicators of youth.

On the other hand, poor eye care can result in problematic eyes at an earlier age. However, cloudiness, irregular irises and damaged vision are always a telltale sign of the passage of time.

We all want our kittens and kittens to have a healthy, shiny and soft coat, but despite the care we lavish on our cats, their skin and hair suffer as they age.

Dry, flaky and thick fur is a common sign of old age. Visible patches, thin hair and gray strands indicate that the cat is very advanced in years.

Some races such as Sphynx have more sensitive skin. As such, adverse weather conditions affect them more easily than other breeds and can fool you into believing that the cat is older.

Some races are more muscular by default. However, as felines age, they begin to lose their well-defined muscle tone. Older cats are more kind and often show signs of hanging skin.

Kittens and young cats are better built and more muscular because they are more active than their adult counterparts.

Of course, various diseases, boredom or feeding can affect the muscle tone of cats of any age.

How to extend the v>

Even if we want them to live forever, cats have a life expectancy that ranges between 12 and 15 years. To increase longevity (there are examples of felines that lived until age 21) we must pay close attention to their care.

As a first step, comply with animal hygiene and health. Food according to your needs, clean water in the drinking fountain every day, periodic deworming, complete vaccination plan and flea removal is part of the basic care.

On the other hand, castration has many advantages in pets, since it prevents the transmission of sexual diseases and also the spread of viruses when males fight. A castrated female is less likely to suffer uterine tumors. In males avoid urethral problems.

How long do domestic cats live

Male cats they usually live between 12 and 14 years. If it is a female, one or two more years should be added. However, cats that live inside houses can reach the age of 21 or more. Sterilization increases the life expectancy of these animals, since the possibility of suffering testicular cancer in males is reduced. Regarding females, they cannot develop uterine or ovarian cancer, and both reduce the risk of breast cancer.

  • Observe the cat: It is very important, since in this way we can realize that something strange is happening in their behavior. Do not drink water? Have you lost your appetite? Has the coat changed you? Doesn't he clean up? If so, it surely suffers from some disease.
  • Go to the vet: It is crucial to carry out periodic checks of the animal, keep it up to date with vaccinations and deworm it.
  • Adequate food and always avoiding being overweight.
  • Encourage you to exercise: Play with him and keep him from lying all day.

Domestic cats

You have to feed them with food that has low amount of preservatives added. Avoid eating chocolate, since, in general, it causes stomach problems for all pets. What you can feed him are fruits, such as apples and pears (as long as they are cut into small pieces). Regarding vegetables, they take them to purge the stomach. They should never be given dog food.

Life cycle and pregnancy of cats

When they reach 4 or 5 months of age, the cats already reach the sexual maturity. In males this happens a little later (specifically, at 6 or 7 months).

The pregnancy takes between 65 and 67 days, born between 1 and 10 offspring.

A one-year-old cat is more or less comparable, in terms of development, to a 15-year-old teenager. In the later years of the life of a cat, fewer years are progressively added to its age compared to humans, so a 15-year-old cat is equivalent, in its development, to a 76-year-old human being. age.

The hair color of cats

Cats can have only one color in their fur or present the mixture of two colors. In addition, there are them with striped colors or with Siamese colors.

Curiously, only females have three or even four colors on their skin (This also happens in some cats, but it is due to some genetic abnormality).

Origins of the domestic cat

It is believed that cats they began to tame about 9,500 years ago. The Egyptians began to live with them 4 centuries before the coming of Christ. In this way, they could keep rats and mice away from their barns. Such was their veneration for this animal that it was forbidden to kill them. Even some of their gods represented them with the face of this cat.

🐱 How old is a cat?

There are several theories (some of them wrong) that talk about what things influence to know how old is a cat. Here we will explain what is the life expectancy of a cat and what things can you do to make your pet live with health as many years as possible.

There are cats that can live 24 years and even something else.

In order to calculate correctly how long is a cat and know the longevity, a clear separation or differentiation between two groups of animals should be made:

  1. Domestic cats
  2. Stray cats

The Average life expectancy of a domestic or domestic cat is estimated at about 13 years. This age can even reach 20 years, or more, if the pet receives veterinary treatments, good care and good nutrition (see how to feed my cat).

Instead, the Average life expectancy of a stray cat or Creole is calculated in about 7 years. It is much lower than in domestic cats, as they face many more risk factors, worse feeding and many more diseases. Let's see it in detail:

How long does a domestic cat live

As we have commented, the average years of life of homemade cats It is quite high due to the good care that these beloved pets usually receive from their masters, apart from pampering and petting (see Why do cats purr).

Therefore, it is easy for them to reach 13-15 years of age. But it is not strange that under optimal conditions you can reach 18 or 20. The oldest cat in the world is currently one called Corduroy, and he is 26 years old.

A balanced and adequate nutrition, makes our beloved felines enjoy many more years of life. Another fundamental point is the regular visits to the vet to control your health, vaccines, deworming and medical care. Without a doubt, they not only live longer, but your pet has a better quality of life.

How long a stray cat lives

On the opposite side we have to the cats that live on the street. These animals are constantly exposed to a multitude of dangers and risks that cause your life expectancy is less. You may be interested in reading: Why cats have 7 lives.

We find factors such as falls from heights or abuses, which undoubtedly negatively influence the age a tramp cat can reach. It is not strange to see cats limping in the street, with wounds, and even unfortunately, killed for these reasons.

On the other hand, we have the weather conditions They may suffer. When living and sleeping on the street, they are exposed to extreme heat or cold, rain, humidity, dirt, etc. If they get sick, it is very difficult for them to receive the veterinary care and treatments they need.

It can also be a determining factor, in cats, the times they have given birth or had puppies. This is so since it involves wear on your body. The more times she has become pregnant, her life expectancy is reduced. Here you can know if a cat is with jealousy.

Last but not least, it comes into play feeding which plays a fundamental role in knowing how long does a cat live.

They obviously drink and eat what they find on the street, including small rodents like mice, or junk food. In most cases suffer from malnutrition and can suffer multiple diseases and infections due to what they ingest.

Currently, scientists continue to study to better understand and know how long cats live, both male and female. By the way, you may want to read at the end: How to know if a kitten is female or male.
