Have you ever wondered how old your cat is in human years? You may have heard that one cat year is equivalent to seven human years, but this is not accurate. Cats mature much faster than humans in the first couple of years of their lives, and then their aging slows down.
What is a Cats Year?
A cat year is a unit of measurement that estimates the equivalent age of a cat in human years. It is based on the average lifespan and developmental stages of cats and humans. However, there is no definitive formula for calculating cat years, as different sources may use different factors and assumptions. Therefore, the results may vary depending on the method you use.
How Old is My Cat in Human Years?
One of the most common methods to convert cat age to human age is to add 15 years for the first year of life, then add 10 years for the second year of life, and then add 4 years for every cat year after that. This means that by year two, a cat has matured to about the same age as a 25 year old human. For example, a 5 year old cat would be 37 in human years, and a 10 year old cat would be 57 in human years.
Another method: Which is based on the book: The Cat Bible by Tracie Hotchner, uses a slightly different calculation:
- 1-month-old kitten = 6-month-old human baby
- 3-month-old kitten = 4-year-old child
- 6-month-old kitten = 10 human years old
- 8-month-old kitten = 15-year-old human
- 1-year-old cat = adulthood, the equivalent of 18 human years
- 2 human years = 24 cat years
- 4 human years = 35 cat years
- 6 human years = 42 cat years
- 8 human years = 50 cat years
- 10 human years = 60 cat years
- 12 human years = 70 cat years
- 14 human years = 80 cat years
- 16 human years = 84 cat years
According to this method, a 1-month-old kitten is equivalent to a 6-month-old human baby, a 3-month-old kitten is equivalent to a 4-year-old child, a 6-month-old kitten is equivalent to a 10-year-old human, and an 8-month-old kitten is equivalent to a 15-year-old human. After that, a 1-year-old cat is equivalent to an 18-year-old human, and then every human year is equivalent to 5 cat years. For example, a 5 year old cat would be 40 in human years, and a 10 year old cat would be 60 in human years.
How Many Cats Years are in a Human Year?
As you can see, there is no simple answer to this question, as different methods of conversion may yield different results. However, using the first method mentioned above, we can estimate that one human year is equivalent to about 4 cat years after the first two years of life. Using the second method from The Cat Bible, we can estimate that one human year is equivalent to about 5 cat years after the first year of life.
Cat Age Chart
To make it easier for you to compare the two methods of converting cat years to human years, we have created a table that summarizes the results for different cats ages:
What Is The Average Cat’s Life Expectancy?
The average lifespan of a cat depends on many factors, such as breed, health, diet, environment, and whether it is an indoor or outdoor cat. According to the American Veterinary Medical Association, the average lifespan of an indoor cat is 10 to 15 years, while the average lifespan of an outdoor cat is 4 to 5 years. Some breeds, such as the Siamese and Manx, may live longer than others.
Why is it Important to Know a Cat’s Age in human Years?
Knowing a cat’s age in human years can help you understand its developmental stage and provide appropriate care for its needs. For example, kittens need more frequent feeding, socialization, and vaccinations, while senior cats may need more regular check-ups, dental care, and special diets. Knowing a cat’s age can also help you detect any signs of aging or health problems that may require veterinary attention.
How to Find Your Cat’s Age
If you are not sure how old your cat is, there are some clues that can help you estimate its age. These include:
Teeth
Cats begin developing baby teeth (deciduous teeth) at three to four weeks of age and have a full set of teeth by six to seven weeks, according to Advanced Animal Dentistry. At around three months, they lose their deciduous teeth. By six or seven months, they will have 30 adult teeth. Dental development is the best way to determine age. However, your veterinarian can still use clues such as wear and tear and tartar buildup to estimate your cat’s age.
Coat and Skin Health
Healthy aging may include a slight dullness of the coat and a decrease in skin elasticity. When older cats experience joint or dental pain, they may groom less frequently.
Muscle Condition
Cats lose muscle mass as they age, particularly along their spine, shoulder blades, and thighs. To estimate age-related muscle loss in cats, veterinarians often refer to the World Small Animal Veterinary Association’s (WSAVA) Muscle Condition Scoring Chart. Your veterinarian can also evaluate your cats for mobility issues or joint pain.
Eye Health
Your veterinarian may examine your cat’s eyes to help determine their age. You can determine their age by the lens in their eyes. Senior cats may also experience iris degeneration or develop a slight cloudiness in their eyes.
