Table Age of a cat by human standards


Determine the age of a cat or a cat by appearance, weight, whiskers, teeth, and behavior. It is better to use several methods at once to minimize the probability of error. Observing the animals will help to establish the exact age of the cat. To do this, it is recommended to have a special diary and record information about changes in the appearance and behavior of the pet.

Determining the most accurate age of a kitten or an already adult animal will allow you to choose the right food, ways of care and calculate the dosage of drugs.

It is necessary to create comfortable conditions for the growth and life of the animal. On this depends on his proper physical development and behavior.

It is especially important to know the exact age of the animal if the pet needs treatment. When choosing a drug, consult a veterinarian!

Compared to humans, felines grow up very quickly. If the cat is one year old, then he is already considered an adult.

There are several ways to determine the age of the animal at home. External signs and behavioral features are taken into account.

In appearance, usually determine the age of the kittens. If the kitten is not yet three weeks old, his head looks disproportionately large compared to the body. A kitten in one month will look more proportional, but the ears will remain small. At one and a half months, the kittens' eyes acquire a bluish tint. By two months, the body becomes longer, and in three or four months the ears grow.

All these changes will be clearly visible to those who are often watching the pet. For this it is recommended to keep a diary. Make notes there preferably at least twice a week.

To determine the age of a kitten by weight is also quite easy. It is recommended to use kitchen scales if the kitten is still small. For accurate weight determination, it is desirable that the kitten does not move. Weight gain in kittens is as follows:

  • if the kitten is not even a week old, it will weigh no more than 115 grams,
  • at the age of 1-2 weeks the weight will be within 170 grams,
  • at the beginning of 3 weeks the kitten will weigh up to 220 grams,
  • in 4-5 weeks the weight will be about 230-450 grams,
  • a kitten in 2 months weighs from 680 to 900 grams.

You must ensure that the weight of your animal does not exceed the norm.
This will help proper nutrition. It is necessary to take into account not only the age of the animal, but also its breed and lifestyle.

Cat whiskers have a very important function. They help them navigate in space.

Whiskers, too, give the age of cats. Especially if they have a single color. After nine years, the whiskers begin to turn gray, and among the dark ones, light vibrissae become visible.

This method is more complicated, but gives the most accurate information.
The teeth can be used to determine the age of both a small kitten and an adult cat. Kittens need to pay attention to the eruption of milk teeth and their loss. They appear at the age of one month and fall about six months. At the age of one and a half the teeth turn a little yellow.

An adult cat needs to compare different types of teeth. It is important to determine how much the incisors are cut. If they have an uneven edge only on the lower jaw, then the cat is about 2.5 years old. If the upper jaw, too - 3.5 years. The cat is over 5 years old if it has fangs. Cats start falling out of teeth after 10 years, and after 15 years even fangs fall out.

In each period of life, the animal develops certain habits. According to him, you can also determine the age of the pet.

Like people, cats have their own individual character. Therefore, this method is not accurate. It is proposed to use it as an additional method for determining the age of the cat.

There are basic signs of age characteristics of a kitten. If he reacts very weakly to external stimuli or does not react at all, then he is not three weeks old. In one month, the kitten begins to walk confidently, be interested in its surroundings, shows interest in games. At five weeks, the kittens begin to run, coordination improves, activity increases. At seven or eight weeks, the pet is already actively communicating with people and other animals.

At five months, puberty begins to occur, which affects changes in the behavior of the pet. The cat starts to meow loudly and try to get out into the street. From five to seven months, there are changes in the appearance and behavior of the animal. Already by seven months, the pet acquires puberty.

To find out the age of a cat in relation to a human one, one often uses the method of multiplying the years of life by seven. But this method is not suitable for pets older than 5 years. The table of the age of the animal by human standards to four years (the age of the cat on the left, the person on the right - man)

How to determine the age of the cat

Cat owners don't always know its exact age. Often, the animal gets to the new owners from the shelter or from the street. If you got a very young child or teenager, then determine the approximate age can even a layman. But most often such questions arise when a fully mature animal enters the house.

An experienced breeder or veterinarian can determine the age of an adult cat with an accuracy of one year. For this you need to study the teeth of the animal. In a month-old kitten, teeth only appear; in a half-year-old, dairy ones are replaced by indigenous ones. Next, look at the erase incisors of the upper and lower jaw, canines. The more worn teeth, the older the animal.

How to draw analogies

How to determine the age correspondence between a cat and a man? The intelligence of man and animal cannot be compared, they are also very different in their physiological development. Therefore, when comparing ages, emotional and social features are primarily taken into account.

For example, both cat and human babies are helpless creatures that depend entirely on the mother. The teenager is active, but has little experience. And the old man gradually loses interest in life, becomes passive, loses the sharpness of feelings.

According to this principle, scientists have compiled a comparative table "The age of a cat by human standards." There are several different age translation systems. The simplest is to multiply the age of an animal by 7. It is easy to be convinced of the uselessness of this method. How can you compare a year old, already mature and independent cat with a seven year old child?

Therefore, the table “Age of a cat by human standards” has been improved. In her one-year-old cat is compared with a fifteen-year-old adolescent, and an animal of two years with a 24-year-old man. In the future, for each cat year is given 4 human.

According to another system, until a cat reaches the age of five, each year it is counted as seven human, up to twelve — four, and after — three. The most accurate system uses a number of complex coefficients. To better understand the development of the animal and compare it with the person, consider the stages of maturing cats.


A cat develops and matures much faster than a human. The period of infancy in a kitten lasts only a few weeks, while the baby makes a big step in its development. A feline child is born absolutely helpless, deaf and blind.

During the week after birth, the film protecting the baby’s delicate ears disappears. The eyes open on the 5-10th day after birth, but the vision is formed gradually, and the kitten will begin to see the world around normally only after a few weeks.

Have a two-week kittens begin to cut teeth. For comparison: in human children this stage occurs only at the age of 6-8 months. Already monthly kittens run, actively study the surrounding space. Children behave like this in 1-1.5 years. The table “Age of a cat by human standards” indicates that a one-month kitten is developed as a six-month-old baby, two feline months are ten human, and a three-month-old animal can be compared to a two-year-old baby.

Young cats develop so rapidly that during this period it is most difficult to compare their age with the age of their children. After three months of age, the kitten actively communicates with its brothers and sisters, establishes contact with the owners. Recognizes its own and others. He can take care of himself, clean his fur, learn certain rules of behavior, focusing on the mother. The kid feeds on its own, knows where the bowls are, the sleeping place, the tray. He already has an idea what you can play with and which items should not be touched.

The age of a cat according to human standards (the table is presented by months in the article) shows that in the first year of its life an animal goes through stages that a person will undergo for 18 years.

Compared to humans, a cat in a short period of two to three months grows up by several years. If a three-month kitten is compared with a baby of 2-3 years old, then a six-month-old kitten looks like a fourteen-year-old. Therefore, it is important not to miss this short period and actively engage in raising a pet. Right now he learns the rules of behavior that will be used throughout his life.


Inexperienced owners can treat kittens like little three-year-olds. They forgive them pranks, aggression, puddles, damage to things and expect that with age, bad habits will disappear by themselves.

The table “The age of a cat by human standards” shows that in fact a five to six month old kitten is comparable to a developed teenager. In the nature of the animal appear serious changes. He becomes active, playful, and sometimes really resembles a teenager at a transitional age.

Fluffy kitten looks cute, and his bad behavior is often forgiven. However, a young animal in adolescence is experiencing the limits of what is permitted. The master must be firm and prevent rebellion.

At this age, cats begin puberty. Cats begin to "flirt" at the age of 5-7 months, they begin the first heat. Cats are also able to mate. May come pregnancy. However, such young animals are not yet ready for parenthood, therefore matings should not be allowed.

So, the age of a cat by human standards (the table up to a year is given below) will look as follows.

The table “Age of a cat by human standards” shows that a one-year-old animal can be compared to an 18-year-old man. This is the age that corresponds to psychological and physical development. The cat seems adult and serious, but often behaves like a child, plays a lot, hides, etc.

The cat has already grown to an adult size, has lost the children's furry fur, its movements no longer seem ridiculous and clumsy, and grace and rapacity appear.

The speed of maturation depends on the breed of cat. For example, eastern breeds are formed early and are fully developed already a year. But large breeds can reach maturity only 1.5-2 years.

How to calculate the age of a cat by human standards? The table indicates that a cat at 18 months (1.5 years) corresponds to a 20-year-old person. Comes youth, the heyday of cat life. It lasts up to 5 years, which corresponds to 36-40 years by human standards.

During this period, the cat is stronger than ever, dexterous and tireless. It is animals of this age that most often become exhibition winners, they are best suited for breeding. At the age of 7, purebred pets are already taken out of breeding, as the risks to the mother and offspring increase.

When does a cat mature in human terms? The table states that the period of maturity falls on 6-10 years, which corresponds to the age of 40-56 years in humans. An adult animal can also play and fool around, but most of the time it behaves solidly and sedately.

The activity and playfulness of a cat depends on its origin. There are breeds that behave like kittens until old age. But regardless of the activity in adulthood, flaws in the content begin to manifest themselves, the first bells of chronic diseases appear. There are failures in the kidneys, liver, gastrointestinal tract. Animals that have not been sterilized, suffer from hormonal disorders.

Veterinarians consider the animal aged 10-12 years to be elderly. However, the venerable age does not mean the approach of death. Much depends on the conditions of detention and heredity. Cats living on the street, usually do not even reach 10 years. But pets often cross the 16-year milestone. Many cats live to 20 years, which corresponds to the 100th anniversary of the person.

Therefore, do not be afraid of old age, equaling the age of a cat by human standards. Photos show that even twenty-year-old pets look and feel great. For cats, old women require special care. Do not expose the animal unnecessary stress, change the position of the bowl, bedding, tray. Keep your pet safe when he becomes clumsy.

It will help to determine the age of a cat by human standards table by year. Photos of furry handsome men will prove to you that they look charming at any age.

Long-lived cats

It is documented that a cat can live up to 29 years. However, there are long-livers, whose age was determined by the testimony of their owners. This mongrel pets who did not receive documents at birth. So, the fluff cat from Texas lived for 38 years, and Lucy, a resident of Foggy Albion, celebrated her 40th birthday.

It is always interesting to know how old a pet would be if he were a man. Such a comparison allows owners to better understand the caudate friend and provide age-appropriate care.

Determination of age as the teeth

Determining the age of a pet by the state of the teeth is perhaps the most frequent way to solve this issue. The teeth of cats of absolutely any breed are identical, for this reason, the method of assessing the age of a cat by the general condition of the teeth, as well as their presence, is the most universal.

Age of kittens is determined by the number of teeth. One has only to know the correspondence of the age of the cat to the period of growth of milk teeth, or the period of their change to permanent teeth.

Kitten age and teeth growth:

  • The period from the second to the fifth week - there are incisors.
  • Period from the third to the eighth week of the week - fangs appear.
  • Period from the fifth to the twelfth week - molars appear.
  • Starting from the third to the fifth month - change of milk teeth to permanent ones.

The state of the oral cavity in adult pets depends in part on their lifestyle and living conditions, as well as on their diet. An important role is played and care, as well as features of cat breeds. Some breeders regularly brush their teeth to their pets and limit their diet in favor of a healthy diet, which has a positive effect on the condition of the teeth and the entire body of the cat.

If it is necessary to determine the age of a cat with already formed teeth, a set of age-related changes in tooth enamel (yellowness, plaque), condition or the presence of incisors, the presence of dental deposits, as well as a number of other signs from the list below form.

To determine the age of the cat in the teeth, you can rely on the following signs:

  • In one year, all the teeth are in good condition, with the exception of damage to the integrity of the tooth during an injury.
  • Starting with one and a half years - signs of yellowness on the enamel appear.
  • Upon reaching two years, the middle and central incisors located on the lower jaw are erased.
  • Two and a half years - signs of dental deposits.
  • At four years, the middle and central incisors located in the upper jaw begin to wear out.
  • By the age of five, signs of friction appear on the canines.
  • In seven years, the central and extreme incisors on the lower jaw are being erased.
  • From eight to nine years - central and middle incisors located on the upper jaw, with obvious signs of abrasion.
  • Ten years - the beginning of the period of loss of the incisors of the lower jaw
  • Twelve years - the beginning of the period of loss of the incisors of the upper jaw
  • From thirteen to fourteen years - the absence of all incisors
  • From the age of fifteen the cat loses its canines, the teeth may be completely absent.

Judging by the above lists regarding age-related changes of a cat's teeth, it is not difficult to find out how many years your pet has. To date, this method is considered the most accurate, but you still need to consider it in conjunction with other signs of age-related changes in the animal.

Cat age by eyes

The age of a cat can be determined by its look. If for young cats the manifestation in the sight of interest and curiosity is considered to be a sign of good state of health, then for mature cats a calm and attentive look becomes the norm.

Like people, in cats, along with other age-related changes, the lens of the eye acquires characteristic signs. With the return of it dims, which can be explained by the possible development of cataracts. Imposes its imprint on the cat's eyes and iris, which also dim with age, sometimes spots or patterns appear on it.

Purulent discharge from the eyes is a frequent problem of cats in advanced age. Иммунитет животного к инфекциям с возрастом несколько ослабевает, поэтому при наличии выделений или повышенного слезотечение нужно обратиться к ветеринару. Конечно, глазная инфекция может быть и у молодых кошек, но в пожилом возрасте пушистые любимцы страдают этим недугом намного чаще.

Оценка возраста кошки по состоянию меха

The fur of an animal has a different degree of thickness, not only depending on the season, but also on the number of years lived. Of course, cats are not prone to baldness, but standing wool can say a lot about the lifestyle and age of the pet. Guided by the following points can be done not difficult conclusions:

  • Young cats have thick and smooth to the touch
  • In older animals, the wool coat becomes less frequent and the fur is harder.
  • Cats, like humans, may show signs of gray hair with age.

In an adult animal

How to determine the age of a cat in the teeth, there is nothing difficult, knowing the signs of abrasion of the working surface at a certain period of life. After one year, the natural process of aging and destruction begins, the signs of which indicate a particular age of the pet:

  • Signs of abrasion on the central incisors, yellowing of the enamel barely noticeable. There are no signs of destruction on other teeth. This situation is typical for a 2-year-old animal.
Abrasion incisors
  • The abrasion of the central incisors on the upper jaw is clearly visible. The initial wear processes on the canines are noted. A yellowish patina is clearly visible on all teeth. This picture can be observed when examining the oral cavity of a cat aged from 3 to 5 years.
  • There is an erasure of the central and middle incisors in the upper and lower jaw, in some cases the incisors have already fallen out. There is a significant yellowing of all teeth. There are cracks and tartar. Such signs are typical for a pet aged from 5 to 10 years.
  • At the time of reaching 10 - 12 years, many cats have a loss of central incisors.. Teeth are usually intense yellow.
  • The absence of all incisors, a significant abrasion of molars indicates that the pet has crossed the 15-year milestone.. If the fangs are missing, the cat is more than 15 years old.

Before you determine the age of a cat on the state of the teeth, you should know that the processes of abrasion of the working surface of the incisors largely depend on the living conditions and the state of health of the pet. Proper bite, care for the oral cavity, a balanced diet for minerals and elements slow down tooth loss.

Determining the age of the eyes is important for small kittens, to apply this method to adult pets is not possible due to the characteristics of biological development. How to determine the age of a cat from the first days of life is important for maintaining the diet of newborn animals, for example, without mothers.

On the first day the newborn kittens are blind. Approximately at the age of 7–10 days eyes begin to open. Already open, but narrowed eyes indicate a 2 - 3 week old babies. By 3 - 4 weeks of age, kitty eyes are already fully open.

The age of the kitten can also tell the color of the eyes. As a rule, instability staining of the iris is observed at the age of 6 - 7 weeks.

As wool and skeleton

Many owners are interested in how to find out the age of a cat by the state of wool and general appearance. To determine whether an old or young animal is taken into the house, it is enough to pay attention to the coat. Small kittens and young pets up to one year old have a very soft and fluffy coat.

Assessing the condition of the coat of a young animal, the owners note the presence of a thick and shiny coat. Each villus has a clear color, which generally results in a well-viewed design. Gray hair is missing.

In cats older than 5–6 years, duller coat is observed, the outlines of the color pattern are not so clear. The cat fur coat itself is not as thick and soft to the touch as that of a young animal. With age, the coat becomes more dense and smooth. After 6-7 years, when examining individual hairs, gray hair can be detected.

In addition to changes in coat, with age, the animal is aging and the musculoskeletal system. As a rule, up to six - seven years old, and in some active pets and up to the age of ten, there are no obvious signs of a change in the skeleton.

Owners often want to know how to find out the age of a cat according to the state of the musculoskeletal system. Young kittens are characterized by uneven body development. The adolescent appearance of the animal, as a rule, is reduced to excessively long limbs, large ears, irregular proportions, which give a lanky and incongruous appearance.

With age, an animal acquires strong muscles, becomes proportional and meets the criteria of a particular breed. At young the muscular relief is observed. Pet movements are filled with strength and grace. The walk is light and relaxed. A young cat easily overcomes obstacles, gracefully performs jumps.

After 7-8 years, the cat's skeleton begins to undergo changes. Older pets have sagging of the spine, bulging blades. Gait is not as easy as at a young age. Muscles become flabby, their volume decreases. Older animals are often thin.

Of course, it is impossible to determine the exact age of a pet by such criteria as the state of the hair and skeleton. But you can say for sure, a young animal or an old one.

Determine age by weight

How to determine the age of the cat by weight, there is nothing difficult for the curious owner. Knowledge of certain parameters will allow one to fairly accurately assume the age of a young animal under 1 year of age:

  • at birth, the baby weighs about 85-100 grams,
  • at the age of 7 days the calf's weight is on average 160 - 170 grams,
  • with a kitten weighing 200 grams, it is safe to say that he is 2 weeks old,
  • at the age of one month, the kitten weighs from 290 to 380 grams,
  • by the 2nd month the baby can reach 1 kg,
  • 1.5 kg weight is recorded in 3 month old kittens,
  • at 4 months the kitten must weigh at least 2 kg,
  • if the scale shows 2–3 kg, then the age of the young animal is 5 months,
  • six month old kitten weighs about 3 kg.

Of course, the weight of the baby depends on the breed, on the quality of food and the conditions of the animal. Nevertheless, this method can be adopted in determining the age of a young pet.

Behavior and age

If you have to figure out how to know the age of the cat, the owner should pay attention to the behavior of the pet. Small kittens and young animals are notable for their activity, love for games and entertainment. Curiosity, playful mood, fear of unfamiliar things and sounds are inherent in young pets under the age of one year.

By the 9th - 10th month, as a rule, the completion of puberty occurs. This moment can also become one of the criteria for determining the age of a pet. At the same time, you should know that long-haired and large breeds mature later.

Mature cat's age is associated with its activity. An animal is characterized by agility, tirelessness. Most of the time, pets are happy to take part in games that actively hunt.

In the elderly and elderly, cats often prefer to sleep, rest, do not want to play. The animal is burdened with chronic diseases and reluctantly participates in entertainment.

The age of the cat and man

Many people are interested to know how to determine the age of a cat by human standards. This question is far from idle. Knowledge of the ratio of feline and human years makes it possible to adequately and competently approach the processes of raising a pet, its maintenance and feeding.

It is considered that one year of a cat is equal to 7 years of human life. This statement is approximate and can be applied to an adult animal. In young people, development occurs much more intensively, and at the age of 6 months the kitten corresponds to a teenager of 14 years old.

"The age of majority" occurs in cats at the age of 1 year, which corresponds to the human 18 years. In 2 years, the animal in terms of its physiological development corresponds to a person in 24 years.

To bring the cat's age to human from 3 to 12 years of age, 4 years should be added each year. Thus a cat by the age of 12 corresponds to 60 years of human life. After the cat reaches 12 years old, 3 years should be added to its years. And if we consider that the average age of a fluffy pet is 15 years, by human standards this age is almost 70 years.

This kind of recount helps in the first place to properly educate young kittens up to 1 year. Many owners make the mistake of thinking that a half year old cat corresponds to the age of a small child.

In fact, in this period, special attention should be paid to schooling the correct manners and behavior of the animal in the house. By analogy with adolescence in humans, raising a kitten from 6 to 12 months is the most crucial period in the life of an animal.

It is important for the owner to know the age of his furry pet. This information will help you to properly feed a little kitten left without a mother, properly raise a young animal, provide a rational diet and care in accordance with the pet's age. If it is not possible to determine this indicator on your own, you should contact a veterinary specialist for help.

Body condition of a cat

Age-related changes affect the entire body. If at the initial stage of life the body of an animal is well developed, which is due to its young age and constant physical activity, then in old age the cat's body noticeably weakens.

An assessment of a cat’s body condition can tell a lot about its past years.:

  • Young cats are muscular and thin
  • Middle-aged cats are not as active and usually well-fed, but the muscular corset is still well formed.
  • Cats that have a dozen years past their shoulders can stay plump. But their age is given by the bones of the shoulder girdle, which begin to bulge strongly. In very old cats, the skin becomes flabby and begins to sag, forming wrinkles and folds.

Cat behavior

You can find out the age of a cat by its activity. The influence of age affects not only the appearance of a pet, but also its habits. Young cats, just started their life path, inquisitive and playful, they are interested in everything new. Middle-aged cats already have life experience, they still show interest in everything new, but they are very careful and have established habits. Older cats are also not deprived of interest in the world, but can no longer actively move and sleep more often than awake.

Cats with age often begin to show aggression towards strangers, this is due to increased anxiety and fearfulness. Also, older cats often suffer from a number of chronic diseases, which worsens their well-being, and interacting with a curious stranger seems to them to be not the best idea against the background of general malaise.

Toilet tray and cat age

If a young cat refuses to use the toilet tray, then this problem may have several constructive solutions, but what if the adult cat began to refuse to defecate in the place allocated for these needs? There may be several reasons for this.:

  • Stress. Older cats are very sensitive to changing situations. Even changing the usual filler for another can create discomfort.
  • The cat may begin to walk past the place reserved for its needs due to vision or smell problems.
  • Kidney and liver disease, urinary tract inflammation often leads to untimely bowel movements, in which case the cat, in addition to health problems, may begin to experience feelings of guilt and fear of punishment. It is better not to aggravate the situation and create the most comfortable conditions for the animal.

The ratio of the age of the cat and man

Although this item is not the determining age, but many owners are asking this question. Everyone knows that with age a person loses a number of abilities that are inherent in a young body. The aging of the cat's body, unfortunately, is inevitable and it occurs much faster than in humans.

The most common way of comparing the age of a cat and a man is multiplying the total years of a cat by the number seven. However, many felinologists disagree with this method and believe that to determine The age of the cat can be compared by the age of the pet and its owner according to the following principle.:

  • A cat at the age of one year - a man of fifteen years old
  • Two-year-old cat - twenty-four year old man
  • Starting from three years to twelve - one year to four
  • After twelve years - each subsequent year is equal to three years.

Thus, it turns out that the cat reaches middle age at about eight years of age. But this figure is by no means accurate, because proper care and a balanced diet largely determine the state of the feline body and directly affect the lifespan of a furry pet. Therefore, many cats live much longer than twelve - fifteen years, while remaining active and life-loving.
