How many cat years is 1 human year

How many human years of life does the age of my cat match? This is a question many people ask themselves. Once upon a time, a simple calculator was popular, according to which each year of a cat’s life matched the seven years of a person’s life. Unfortunately, the matter of cat’s age is not so simple…

How to count the age of a cat? First of all, the childhood of a cat – compared to ours – is very short. Therefore, during the first two years of life, changes corresponding to changes in the human body occur very quickly and then slow down. In the following years of your cat’s life, you can use a conversion rate according to which each subsequent year is equivalent to four “human” years. However, such a conversion rate should also be treated with a distance – much depends on the state of health of the cat, the environment in which it lives, and even the breed.

The simplest way to roughly convert the age of a cat into human years is as follows:

Cat agePeople age
1 month8 months
2 months ok. 3 years
3 months ok. 5 years
4 months ok. 6 years
5 months ok. 8 years
6 months ok. 10 years
7 months 10 years 10 months
8 months 11 years 8 months
9 months 12 years 6 months
10 months 13 years 4 months
11 months 14 years 2 months
12 months 15 years
2 years 24 years
3 years 28 years
4 years 32 years
5 years 36 years
6 years 40 years
7 years 44 years
8 years 48 years
9 years 52 years
10 years 56 years
11 years 60 years
12 years 64 years
13 years 68 years
14 years 72 years
15 years 76 years
16 years 80 years
17 years 84 years
18 years 88 years
19 years 92 years
20 years 96 years
21 years 100 years

What affects the age of a cat?

It should be noted that this conversion rate of cats to human years applies to cats not coming out or going out only on a leash or to a secured garden – that is, under the care of a human being, regularly examined by a veterinarian, vaccinated and dewormed, not exposed to fighting with other cats and other dangers or, finally, unfavourable weather conditions, especially cold winters.

In the case of a free-living cat, the first two years of life are the same as in sandwich cats. Later on, however, we can safely say that cats flying freely fly faster than in comfortable four walls. A three-year-old free-living cat can be equated with a four-year-old house cat. And although still at this young age this difference is not yet significant, over the years it becomes more and more fundamental.

A seven-year-old cat staying at home can be compared to a 44-year-old man, but in the case of a free-living cat these seven years may already be equivalent to 64 human years. 10 years for a free-living cat is already 88 years old – so such a cat is already a judge old man, while a domestic caress at the same age is only just entering the world of cat seniors. Eleven- or twelve-year-old free-living cats are already very old.

Not without significance is also the state of health of the cat – cats suffering from chronic illnesses age faster than healthy animals. Life expectancy also depends on the breed and its genetic heritage. Long-lived cats include Burmese, Siamese and Abyssinian cats, for example. In turn, large breeds, such as maine coon, have a very long childhood – they can reach full maturity even at the age of two or three years.

How to determine the age of an unfamiliar cat?

Is it possible to determine the age of a cat on the basis of its external appearance, e.g. when it is found on the street? It’s easy for kittens who have to change their appearance, behaviour and skills during the months of life. Adult cats may find it more difficult to determine their age, especially as their health may “age” after a number of mumbles.

One of the criteria for trying to determine the age of a cat is the condition of its teeth. Milk teeth start to emerge in kittens about 3 weeks old, sometimes a little earlier. An 8-week-old kitten already has a set of milk teeth (26 teeth). The permanent replacement of your kitten’s milk teeth will take place at 3-4 months of age. A six-month-old cat usually has a full arsenal of permanent teeth: 4 canines, 12 incisors, 10 premolars and 4 molars.

The older the cat, the more worn its teeth. Like humans, a lot depends on genetic factors – some cats are more prone to tartar or periodontal disease than others. Generally, however, a young cat has clean white teeth and healthy pink gums. During the second year of life, the teeth will slowly turn yellow, but between 3 and 6 years of age there is the highest probability of tartar build-up. Yellowing is becoming stronger and the back teeth are the first signs of wear and tear. Cats often don’t have some incisors even at this age, but these tiny teeth aren’t the most important for the animal. Until the age of 10, the cat’s teeth show increasing signs of wear and tear (cavities, filleted edges), discoloration and gum inflammation. It is not uncommon for some teeth to be missing.

Both young and middle-aged cats, provided they are healthy and reasonably well nourished, have a supple, firm, well muscled body. The cat begins to lose muscle mass at the age of 8-9 years. An older cat may also have dull and thinned fur – a young, healthy cat with a thick and shiny coat. An old cat may also be reluctant to jump into higher places. If accompanied by walking on stiff feet, these are symptoms of old-age inflammation or arthritis.

Kittens’ paw pads are soft, smooth and soft like rubber teddy bears. Over time, the cushions become harder and rougher – just like a human heel. In cat seniors – ten years old or even older – cushions can be dry, thickened and cracked. Older cats also often have problems with splitting and sometimes ingrown claws.

It is worth remembering that matted and falling hair, bad condition of teeth or other symptoms mentioned above may also indicate a disease – a cured cat often turns out to be younger than its initial condition would indicate. Therefore, determining the age of a cat is an individual matter – when trying to estimate how old a cat maybe, take into account the various factors and conditions in which it has lived up to now. If they do, take them to the vet for an “overhaul”. Your vet will be able to assess your cat’s health and help you determine her age.
