Lifespan Of A Cat In Human Years

Lifespan Of A Cat In Human Years


The speed at which cats age is a hotly debated subject, with the lifespan of a cat in human years ranging from 10 to 20. However, it’s most commonly accepted that a cat’s age is 15 years for their first year of life and 24 for their second. After that, they grow four “cat years” for every one human year. This means your cat will be 28 when you celebrate her third birthday together and 32 by her fourth birthday!

Cat’s Age In Human Years

A cat’s age in human years is one of the most common things people ask about when they get a new cat. In general, a cat ages much more quickly than humans and is considered to be middle-aged at around 7 years old. If your feline friend has lived with you for several years, then consider yourself lucky as there are many statistics that show how long cats live compared to their owners.

In this article we will explain why cats age so rapidly compared to humans and provide some useful tips for keeping them healthy for longer.

1 year old 15 years old

  • 1 year old cat is equivalent to 15 years old human
  • 2 year old cat is equivalent to 20 years old human
  • 3 year old cat is equivalent to 25 years old human

2 years old 24 years old

A two-year-old cat is equivalent to a human at 24 years old, which means they’re at the peak of their physical energy and mental ability. This is also true for your cat—you may notice it interacting with you more often and having more energy than usual as well.

This age is also when cats are most likely to start fighting for dominance in the household, so be prepared for some disagreements between your feline friend and others he or she lives with!

3 years old 28 years old

If you have a kitten, it will most likely be fully grown by the time it is three. By this point, they have reached their stride in terms of maturity and are ready to take on the world. A cat that has reached full maturity by age 3 would be considered an older adult. However, this does not mean that your kitty will start aging rapidly from there on out! The average lifespan for cats is between 15 and 20 years old, which puts them well above dogs (10-13 years) and even humans (79 years).

A cat can live up to 20 years old with proper care and attention!

4 years old 32 years old

A cat is 4 years old in human years when it is 32 years old, or a young adult. Cats at this age are considered teenagers, and they’re usually not quite full-grown yet. Cat’s are at their most active during this time, so you may see them climbing on furniture and running around the house with reckless abandon.

5 years old 36 years old

When you think about it, cats are like teenagers. They’re energetic, unpredictable and have a lot of energy. They’re also curious—maybe even more so than people.

In fact, 5 years old is the equivalent to 36 years old for humans. Cats are just as likely to get into trouble as any teenager would be!

6 years old 40 years old

Six years old is around the time that cats are fully grown and mature. At this stage, they are more independent than dogs and less likely to be playful or lazy. The average lifespan for cats is 12–15 years, but some have been known to live up to 20 years or more.

7 years old 44 years old

To put your cat’s lifespan in human years, simply add 7 to the number of years they have lived (the first year is included).

So if you have a cat that is 7 years old, they are actually 44 years old.

8 years old 48 years old

Eight years old is the age when a cat is considered middle-aged. The average lifespan of a domestic cat is about 15 years, but some can live up to 20 years, so eight isn’t as far away from the end of your pet’s life as you might think.

When you take into account that 8 years old is also when your pet reaches senior status, it might make sense to start thinking about what that means for their future health and well-being.

If you want to ensure your cat has the longest possible life span and quality of life, consider these tips:

9 years old 52 years old

A cat is in its prime at 9 years old. Cats are like teenagers, playful and active, but they’re also curious and friendly. Your cat will still be young enough to get into mischief, but not so young that it will eat anything without thinking twice.

This makes this the perfect time to have your little furball spayed or neutered. This can be done at any age before sexual maturity, which is around 6 months for females and 8-10 months for males. If you wait until after puberty has passed, your pet may need surgery on both sides of their reproductive tract because cats have separate openings for urine and feces (they don’t use their anus as a urinating hole).

10 years old 56 years old

If you’re looking at your cat and thinking he’s looking a bit old, you’re right. On average, a cat can live up to 20 years, but that doesn’t mean it will always live to play with the next generation of kittens.

On average, cats tend to die around 10 years old—or 56 in human years—after which they can expect one more decade of life as a senior citizen before passing away peacefully somewhere between 12 and 14 years old. But knowing when exactly your pet will pass can be difficult without some research: While most cats don’t reach their golden age until 15 or 16 human years old, others live into their twenties! So why do some felines outlive others? And how can you make sure yours lives longer?

11 years old 60 years old

We know you’ve heard this before, but it bears repeating: cats age quickly. If you’re like us, you might think of a cat as a temporary pet who will be around for an average lifespan of 13 years old. However, if your cat has reached 11 years old and is still going strong, that means that he or she has more in common with humans than previously thought! In fact, not only do cats look forward to their next meal—so do we!

Cats are like human children in many ways: they can be stubborn and impatient at times; they have distinct personalities; they grow up fast (in both size and intelligence). They even look like miniature versions of their owners—baby-sized versions with big eyes and huge ears! All this should give you reason enough to treat them as little people instead of just pets…which is good news because there’s plenty more similarities between our species yet to come!

12 years old 64+years old Takeaway : Cats age quickly.

Twelve years old 64+years old Takeaway : Cats age quickly.

When a cat reaches 12 years of age, he or she is considered to be an elderly cat. This means that they are at the tail end of their life and can expect to live another two or three years (although some cats have been known to live into their 20s).


The average lifespan of a cat is approximately 12-18 years. This means that your cat will be around for many years, but the time goes by quickly!
