Most cats live between 12 and 18 years, with indoor cats commonly reaching 14 to 18. Breed, lifestyle, diet, and veterinary care all influence lifespan, and there is a lot you can do to help your cat beat the average.
What Is the Average Lifespan of a Cat?
The average lifespan of a cat is 12 to 18 years, though many indoor cats live well into their late teens or even their 20s. A 2024 study published in the Journal of Feline Medicine and Surgery analyzed nearly 8,000 cats in the UK and found an overall average life expectancy of 11.7 years, though this figure includes outdoor cats and cats that died young from accidents or disease. Earlier UK research found a median lifespan of 14 years for cats receiving regular veterinary care. The lower study averages reflect the full population; a cat that lives indoors, eats a balanced diet, and sees a vet regularly will almost certainly outlive the "average" by several years.
Female cats tend to outlive males by about 1 to 1.5 years. The 2024 study found females averaged 12.5 years compared to 11.2 years for males. Spayed and neutered cats also live longer than intact cats.
Cat Years to Human Years: Age Conversion Chart
Cats do not age at the same rate as humans. They mature very quickly in their first two years, then the pace slows. According to guidelines from the American Animal Hospital Association (AAHA), the American Association of Feline Practitioners, and International Cat Care: a cat's first year equals roughly 15 human years, the second year brings them to about 24, and each year after that adds approximately 4 human years.
Here is a quick reference chart:
Cat's Age | Approximate Human Equivalent | Life Stage |
1 year | 15 years | Kitten |
2 years | 24 years | Young adult |
4 years | 32 years | Young adult |
6 years | 40 years | Young adult |
7 years | 44 years | Mature adult |
10 years | 56 years | Senior |
12 years | 64 years | Senior |
14 years | 72 years | Senior |
16 years | 80 years | Senior |
18 years | 88 years | Senior |
20 years | 96 years | Senior |
A 10-year-old cat that seems perfectly healthy is actually closer to a 56-year-old human and may benefit from more frequent vet visits. It also puts into perspective how remarkable it is when cats reach 20 or beyond.
If you are curious about when cats reach their full size, most are fully grown by 12 to 18 months, though larger breeds like Maine Coons can take two years or longer.
How Long Do Indoor Cats Live vs. Outdoor Cats?
Indoor cats live significantly longer than outdoor cats. The typical indoor cat lifespan is 12 to 18 years, while outdoor-only cats average just 2 to 5 years.
The difference comes down to risk. Outdoor cats face threats from vehicles, predators, fights with other cats, and infectious diseases like feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV). They are also more likely to encounter toxins and parasites.
A 2022 UC Davis study examining over 3,100 cats found that outdoor-only cats had significantly shorter lifespans. Interestingly, cats with supervised outdoor access (catios, leash walks, enclosed gardens) did not have significantly shorter lifespans than indoor-only cats, suggesting safe outdoor enrichment can give your cat the best of both worlds.
If your cat currently lives outdoors, transitioning them to an indoor or supervised-outdoor lifestyle is the single most impactful thing you can do to increase their lifespan.
Cat Lifespan by Breed
Not all cats live the same number of years. Mixed-breed cats (often called Domestic Shorthairs, Mediumhairs, or Longhairs) generally outlive purebred cats thanks to hybrid vigor, where greater genetic diversity reduces the risk of inherited health problems.
The 2024 VetCompass study we talked about earlier confirmed this: crossbred cats averaged 11.9 years compared to lower averages for most purebreds. Burmese and Birman cats were the exceptions, with the highest life expectancy at 14.4 years. Sphynx cats had the shortest at 6.8 years.
Here is a guide to breed-specific cat lifespans. Individual cats with excellent care often exceed these ranges.
Breed | Average Lifespan | Average Age (Years) |
Sphynx | 8 to 14 years | 11 |
Maine Coon | 10 to 13 years | 11.5 |
Abyssinian | 9 to 15 years | 12 |
Bengal | 12 to 16 years | 14 |
Ragdoll | 12 to 17 years | 14.5 |
Persian | 12 to 17 years | 14.5 |
British Shorthair | 12 to 17 years | 14.5 |
Mixed Breed (DSH/DLH/DMH) | 12 to 18 years | 15 |
Birman | 14 to 16 years | 15 |
Burmese | 14 to 18 years | 16 |
Siamese | 12 to 20 years | 16 |
Russian Blue | 15 to 20 years | 17.5 |
Our own 2026 internal Embrace data tells a similar story. Among the oldest cats currently insured by Embrace, the vast majority are mixed-breed domestics, with ages ranging from 20 to 24 years old. A few purebreds, including Himalayans, Ragdolls, and Tonkinese, also appear among the longest-lived, but mixed breeds dominate the list.
How Long Do Tabby Cats Live?
Tabby is a coat pattern, not a breed. The classic striped, spotted, or swirled markings can appear on many breeds and mixed-breed cats alike. Because tabby-patterned cats are very often mixed breeds, they benefit from that same genetic diversity advantage and commonly live 15 to 20 years with proper care.
Factors That Affect How Long Cats Live
Several factors influence your cat's life expectancy, and many are within your control.
Spaying and neutering. According to the AVMA, studies have repeatedly shown that spayed and neutered cats live longer. The 2024 VetCompass study found neutered cats lived an average of 1.07 years longer than intact cats. Spaying eliminates uterine infection risk and reduces mammary cancer risk, while neutering reduces roaming behavior and testicular cancer risk.
Body weight. The same study found that cats at or slightly above their breed's median weight lived longest. For every 100 grams a cat deviated from ideal weight, lifespan decreased by about 0.02 years. That adds up over time, making portion control and regular play important habits.
Diet and nutrition. A complete, balanced diet appropriate for your cat's life stage supports organ function, immune health, and a healthy weight. Kittens need growth formulas, adults need maintenance diets, and seniors benefit from formulas designed for aging joints and kidneys.
Veterinary care. Cats that receive regular checkups, vaccinations, and parasite prevention live longer because problems are caught early. A consistent vet visit schedule is especially important for older cats prone to kidney disease, hyperthyroidism, and diabetes.
Genetics. Some breeds are prone to specific conditions. Persians face higher risk of polycystic kidney disease (PKD), Maine Coons of hypertrophic cardiomyopathy (HCM), and Siamese of certain cancers. Knowing your cat's breed risks helps you plan proactive screenings.
Dental health. Dental disease is one of the most common health problems in cats and can lead to pain, infection, and organ damage if bacteria enter the bloodstream.
Environment and enrichment. Indoor cats need mental stimulation to prevent stress, obesity, and behavioral issues. Cat trees, puzzle feeders, window perches, and interactive play all contribute to a longer life.
Cat Life Stages and What to Expect
Understanding your cat's life stage helps you provide age-appropriate care. The AAHA and AAFP define four main feline life stages:
Kitten (birth to 1 year). The fastest period of growth. Kittens need vaccinations, deworming, spaying or neutering (recommended by 5 months), and a growth-formulated diet. Expect high energy and lots of kitten behavior that gradually calms toward their first birthday.
Young adult (1 to 6 years). Cats are at their physical peak. Annual vet visits are typically sufficient. Focus on maintaining a healthy weight and providing enrichment.
Mature adult (7 to 10 years). Subtle aging signs may appear: slight weight changes, reduced activity, or early dental issues. Your vet may recommend baseline bloodwork to establish normal values for future comparison.
Senior (11 years and older). Vet visits every six months are recommended. Common conditions include kidney disease, hyperthyroidism, arthritis, and dental disease. Monitor weight, appetite, water intake, and litter box habits closely.
As a vet, I can’t stress enough that the importance of regular veterinary care increases as a cat ages. We want to see those kitties in their golden years at least twice a year for routine checkups to get a better handle on subtle changes and to recognize health issues while they’re in the early stages.
How to Help Your Cat Live Longer
You have more influence over your cat's lifespan than you might think. The most effective steps:
Keep your cat indoors or provide supervised outdoor access through a catio or leash walks. This is the single biggest factor in cat longevity.
Maintain a healthy weight. Ask your vet about body condition scoring and feed the right amount for your cat's age and activity level.
Schedule regular vet visits. Annual exams for adults and twice-yearly visits for seniors catch problems early when they are easier and less expensive to treat.
Feed a complete, balanced diet appropriate for your cat's life stage. Avoid overfeeding treats.
Stay current on vaccinations and parasite prevention. Core vaccines and flea, tick, and heartworm prevention protect against diseases that can significantly shorten a cat's life.
Spay or neuter your cat. Altered cats live longer, healthier lives.
Provide mental and physical enrichment. Interactive toys, climbing structures, and regular play keep your cat fit and sharp.
As cats age, vet costs add up. A single emergency or chronic condition can result in bills of $1,000 to $5,000 or more. Cat insurance can help you prepare for both routine and unexpected health issues. Embrace offers accident and illness coverage to help with unexpected injuries, ongoing health conditions, and some breed-related issues. This type of coverage is generally meant for bigger, less predictable vet bills rather than everyday visits.
Routine care works a little differently. Wellness Rewards is an optional add-on that helps you budget for common preventive expenses like annual exams, vaccines, and dental cleanings. Keeping routine care separate from medical coverage can make it easier to plan ahead for both the expected and the unexpected.

The Oldest Cats Ever Recorded
While most cats live into their teens, a few remarkable felines have far exceeded expectations.
Creme Puff holds the Guinness World Record for the oldest cat ever. This mixed breed tabby from Austin, Texas, lived 38 years and 3 days (1967 to 2005).
Flossie, a tortoiseshell from England, is the current oldest living cat as verified by Guinness World Records. She turned 30 on December 29, 2025. Despite being deaf and having limited eyesight, Flossie remains active and in stable health.
Both are mixed breeds, both lived in good homes, and both received consistent care, reinforcing the genetic diversity and lifestyle advantages discussed above.
At Embrace, we currently insure dozens of cats aged 20 and older, with our oldest policyholder at 24 years old according to 2026 internal Embrace data. The vast majority of these long-lived cats are mixed-breed domestics.
