The Age in human years will be displayed.
Although there is no scientific research on the relation of cat years and human years, the general popular consensus is that 1 cat year is the equivalent of 7 human years. Instead, the first two years of a cat’s life has a much faster growth rate than a human child. A cat after one year is the human age of 15 and by age two the cat is around 24 years old. After the first two years the growth rate slows down, with every 12 months in a cat’s life to be the equivalent of roughly 4 human years.
It should be noted that outdoor cats age more quickly than indoor cats. With less exposure to outside hazards, indoor cats are recorded to reach their late teens or even live into their 20’s, as opposed to their outdoor counterparts which may live up to 10 years old.
Many factors are to be taken into consideration when assessing a cat’s health age, including daily diet, the quality of their food, regular vet check-ups and their genetic disposition. This calculator conversion can be useful in learning more about the different key stages in a cat’s life according to its age and how to best cater to them as a responsible feline owner.
Note: This calculator will give you a general comparison of a cat's age converted to a human’s age. Variance may occur depending on your pet’s breed, genetic disposition and day to day lifestyle. An animal’s life expectancy is usually related to its size with smaller animals having a longer lifespan. To get the most accurate comparison, see a veterinarian for the age of your pet.
Indicators of a Cats age
If you are unsure of your cat's age there are various ways to help you determine their age, with several methods used.
Young cats have bright and clear eyes, while a cloudy appearance, tearing or discharge is a sign of a cat in their later year.
An older cats coat will usually be thicker and coarser while a younger cat is generally smoother and softer. It is also possible for an older cat's fur to change color with patches of white or gray similar to humans.
Teeth are a good indicator of a cat’s age, especially younger cats and kittens. Baby teeth first come between two to four weeks, by around 3-4 months permanent teeth start to appear. If you check a cat’s teeth and they have permanent, white teeth, the cat is likely about a year old. Missing teeth and tartar buildup can be an indicator of age, pending the previous owner’s diligence in their cat’s dental hygiene.
Younger cats benefit from their higher activity level with more defined muscle tone, versus an older feline with a more sedated lifestyle, who may display extra skin, weight gain or show protruding shoulders.
