# How to calculate the age of a cat in human years

It is natural for all pet parents to want to know how old their kitten is in equivalent to human years. So how can you calculate the age of your cat in “human” years?

The 7 year rule

You’ve probably heard of the so-called seven-year rule. In fact, you may have even seen it in some graphic table.

In reality, the seven-year rule is false .

This popular misconception basically makes you think that you have to multiply your cat’s current age by seven to get its actual age in human years. Don’t believe this myth!

### So what is the actual human age of cats?

Most of us perceive cats in three ways: kittens, adults, and elderly cats . But there is much more. As the kitten grows and enters adulthood, only 1 human year has passed, but 15 for the cat.

The first (and most important) year of a cat’s life is equivalent to 15 human years .

During the first two months of a kitten, it is already 3 years old in equivalence with a human child. And by the time he reaches two years on the calendar, it’s like he’s almost 24.

After passing the two-year mark, he ages nearly four years per human year.

In other words, when five years have passed, your kitten will be 36.

However, outdoor cats age faster than domestic cats because they are much more affected by their environment and living conditions. As such, a five-year-old outdoor kitten could easily be 48 years old in human equivalent.

So, let’s sum it up. During the first few years of a cat’s life, the cat ages rapidly. After that, the aging process slows downto an equivalent of 1 human year – 4 cat years.

### Calculation table

As you can see from the calculation table above, indoor and outdoor kittens age the same for the first two years of their life. After these two years, the age of the outdoor cat accelerates faster than that of the indoor kitten.

You can use the table to calculate the approximate age of your own kitten in human years .

However, as we mentioned earlier, this box cannot be applied to all kitties. If you adopt a stray cat after it has reached adulthood, its aging will slow down. High-quality cat food, an indoor home environment, and proper care will be significantly better for your cat, and she may live longer as a result.

Regardless of their mischievous nature and short lifespan, cats make our world a better place. If you want to have a feline friend, treat him with all the love and affection you can give. He will appreciate you for your efforts for the rest of his life.
