Cat lives compared to human lives

Q: What is a cats life compared to a humans life?

Although theres no reliable scientific way to calculate the relationship between human and cat years, its generally agreed that the first two years of a cats life are roughly equal to the first 25 of a humans. After this, add four cat years for every human year.

Q: What is 3 cat years in human years?

Then it gets much easier: Each year of a cats life is roughly equal to four human years, so a 3-year-old cat is about 29; a 4-year-old cat is 33; a 5-year-old cat is 37; and a 6-year-old cat is 41. And so on and so on. If your cat gets to 20, shes around 97 human years old.

For their size, cats live quite a long time. Generally, an animal’s longevity is proportional to its size (with the exception of tortoises, man and a few other animals).

According to popular legend, one human year is the equivalent of seven ‘cat years’, but in reality, a one-year-old cat is much more mature than a seven-year-old child. Learn all about your cat’s lifespan and how old they are in human years in this guide.

A tiny mouse has a short lifespan, a rabbit somewhat longer and a dog between 7 and 20 years depending on its breed or size, its activity, or both. Cats aren’t much bigger than rabbits, but whereas the rabbit may live about 8 years, a cat will live on average about 12–14 years, and it’s not unusual for cats to reach their late teens or even their early 20s.

There are 6 life stages for cats:

Kitten – 0–6 months
a period when the young cat is growing rapidly and is usually not quite sexually mature

Junior – 7 months–2 years
during this time the cat reaches full size and learns about life and how to survive it
Prime – 3–6 years
the cat is mature physically and behaviourally, and is still usually healthy and active, looking sleek and shiny and making the best of life
Mature – 7–10 years
the cat is what we call ‘Mature’, equivalent to humans in their mid-40s to mid-50s
Senior – 11–14 years
takes the cat up to the equivalent of about 70 human years
Super Senior – 15 years and over
many cats do reach this stage, some not showing any signs of being so senior in age

The table below shows all of the stages and also the equivalent human age. What these stages let us do is to appreciate how old the cat is inside, since, as has been pointed out, this is often not very obvious from the outside, as cats seldom go grey or show outward signs of pain or illnesses such as arthritis.

International Cat Care has set up a preventative healthcare initiative called Cat Care for Life. The programme looks at the health checks your cat should be having dependant on its age and what age-related changes you can expect to see in your cat.

Although there’s no reliable scientific way to calculate the relationship between human and cat years, it’s generally agreed that the first two years of a cat’s life are roughly equal to the first 25 of a humans. After this, add four ‘cat years’ for every human year. This means if your cat is six years old, their equivalent cat age in human years will be around 41.

How many cat years are in a human year?

The first year of your cat’s life is considered the equivalent of 15 human years. The second year adds nine more human years to the total, which means 2 cat years are approximately 24 human years. After this, each additional human year is around four ‘cat years’.

Don’t worry, we’ve done all the math for you! Check our calculator at the bottom of the page and find out your cat’s age in human years at a glance.

What is the average cat’s life expectancy?

The true answer is that it depends, but indoor cats usually live longer than outdoor cats. The average indoor cat lifespan is 16 to 18 years and some even reach the venerable age of 20.

Life expectancy in cats also varies depending on the breed, as some cat breeds will naturally live longer than others. For example, Siamese and Manx breeds are said to live the longest, so they could reach a ripe age in human years!

Did you know? According to some sources, the world’s oldest cat lived to be 34? That’s 153 in human years! Read more fascinating cat facts here.

Cats’ life expectancies have increased dramatically in the last few decades. Although it’s never enough, we’re spending more and more time together with our feline friends and that can only be a great thing.

How can I tell my cat’s age?

To find out how old your cat is, it’s best to take them to a vet. But you can still look for tell-tale signs of a cat’s age and health.

Teeth

Teeth can’t pinpoint the exact date for your feline friend’s birthday party, but they are still a great indicator of a cat’s age. The milestones are:

A kitten’s first teeth appear between two to four weeks.
Their permanent white teeth come in at around four months.
Yellow stains (aka tartar) on a few teeth can mean your cat might be between one or two years old.
If the stains appear on all teeth, the cat is likely at least three to five years old.
Missing teeth are usually a sign that your cat is a respectable senior, between 10 to 15 years of age.
But keep in mind that some cats can just have worse teeth than others regardless of their age.
