The Secret to a Cat’s Nine Lives. How Old Can Cats Really Live?

Average Lifespan

The average lifespan of an indoor cat generally ranges from 10-15 years, with some cats living well into their 20s. Indoor cats live significantly longer than outdoor cats on average. Studies show that the average lifespan of an outdoor or indoor/outdoor cat is only 2-5 years.[1][2]

Cats who live exclusively indoors are protected from many of the dangers that face outdoor cats, like cars, disease, predators, and territorial fighting. Keeping a cat inside allows for more controlled health monitoring and care from an owner. With proper nutrition, medical care, mental stimulation, and a safe home environment, indoor cats are likely to live long, healthy lives.

Oldest Cats

Some of the oldest cats verified by the Guinness Book of World Records include the following:

The oldest cat ever recorded was Creme Puff, who lived to be 38 years and 3 days old. According to the 2010 Guinness World Records, Creme Puff was born on August 3, 1967 and lived with her owner in Austin, Texas until she passed away on August 6, 2005.

Another famously old cat was Granpa Rex Allen, a Maine Coon who lived to be 34 years old. Granpa was born in Paris, Texas on March 30, 1998 and passed away on his 34th birthday in 2022, according to the Guinness World Records.

The oldest living cat as of 2023 is Flossie, a 26-year-old cat from Orpington, England. According to Guinness World Records, Flossie was born in 1995 and was adopted from a shelter in 2008 by her current owner.

Factors for Longevity

There are several key factors that contribute to a cat’s longevity and help them live a long, healthy life. Proper diet, exercise, and mental stimulation are very important. According to a study from Snappy Tom, a nutritious diet tailored to a cat’s needs at each life stage can add years to their life. Cats who eat high-quality food with the right balance of proteins, fats, and nutrients maintain a healthy weight and have less risk for diseases. Exercise also improves longevity by keeping cats trim and fit. 24PetWatch notes that active playtime and allowing cats to hunt, pounce, and run stimulates their mind and body. Additionally, providing puzzles, toys, scratching posts and other forms of environmental enrichment prevents boredom and gives mental stimulation. Mentally engaged cats have lower stress levels. All of these factors work together to extend a cat’s lifespan.

Medical Care

Medical care from a veterinarian is crucial for cats to live a long and healthy life. Regular veterinary checkups, vaccines, and preventative care can help catch problems early and add years to a cat’s life.

Annual or biannual checkups allow vets to monitor a cat’s overall health and wellbeing. Bloodwork, dental exams, and other tests during routine visits can identify issues like kidney disease and hyperthyroidism before they become more serious. Early detection and treatment of illnesses gives cats the best chance at a normal lifespan.

Vaccines are also important. Core vaccines like rabies, panleukopenia, calicivirus and rhinotracheitis prevent fatal infectious diseases in cats. Certain non-core vaccines may also be recommended based on lifestyle and risk factors. Keeping up with a proper vaccination schedule protects cats from contracting deadly viruses and infections.

Preventative care like dental cleanings, parasite control and nutrition help avoid health problems down the road. Professional dental cleanings remove tartar buildup and reduce bacteria. Regular deworming and flea/tick medication keeps parasites at bay. And feeding a high-quality diet tailored for a cat’s life stage provides balanced nutrition to keep the immune system strong.

With regular vet visits for exams, vaccines and preventative care, cats are more likely to live long and stay healthy into their senior years. Medical care is key to maximize a cat’s lifespan by detecting issues early and keeping preventable diseases away.


Certain breeds live longer than others on average. According to this source, some of the cat breeds with the longest lifespans include:

  • Manx – Average lifespan: 15 years.
  • Siamese – Average lifespan: 15 years.
  • Oriental Shorthair – Average lifespan: 15-20 years.

In general, mixed breed domestic cats tend to live longer than purebred cats on average. However, some purebreds like the Siamese and Manx breeds often live well into their teens or even early 20s. Genetics play a role, with certain breeds being predisposed to longevity.


Getting your cat spayed or neutered can significantly increase their lifespan. According to research from Banfield Pet Hospital, neutered male cats live 62% longer and spayed female cats live 39% longer than unaltered cats 1. When cats are spayed/neutered, they are less likely to roam and get into fights, reducing their risk of disease transmission and injury. The procedure also eliminates the possibility of life-threatening complications from pregnancy and birth. Overall, the health and behavioral benefits of spay/neuter allow cats to live longer, healthier lives.

Providing a safe and enriching environment for cats is crucial for supporting their physical and mental wellbeing, and can help extend their lifespan [1]. Indoor cats who are given access to outdoor enclosures or are walked on a leash benefit from environmental stimulation while avoiding the risks of free-roaming [2]. Creating a stimulating indoor space through cat towers, scratching posts, puzzle toys, and rotating toys helps prevent boredom. Cat owners should also provide clean litter boxes, scratching surfaces, hiding spots, elevated perches, and opportunities for play [3]. Ultimately, an enriched living space allows cats to engage in natural behaviors and enhances their quality of life.



A cat’s genetics play a significant role in determining its longevity. Certain breeds, such as Siamese and Persian cats, tend to live longer than other breeds on average. According to Feline Longevity Research at Basepaws, genetic analysis has shown that cat breeds with higher heterozygosity, or genetic diversity, tend to have increased lifespan. This points to underlying genetic factors that contribute to longevity in cats.

In a 2022 study published in PMC, researchers found that the number of de novo genetic mutations in cats increases with the reproductive age of the parents (Wang et al, 2022). This indicates that cats born to older parents accumulate more mutations, some of which may impact lifespan. While the role of genetics is still being uncovered, it’s clear that a cat’s unique DNA influences its predisposition for a long and healthy life.

Signs of Aging

As cats grow older, there are several key changes to look for that indicate aging. Some of the most noticeable signs of aging in cats include:

Decreased mobility – Older cats may have a harder time jumping up to their favorite spots and may need help accessing litter boxes or getting on furniture. You may notice them moving slower overall. According to Great Pet Care, arthritis is a common cause of mobility issues in senior cats.

Weight loss – Aging cats often lose weight due to lower calorie needs and decreased appetite. Check with your vet if rapid weight loss occurs, as it could signal an underlying condition (Papaya Pet).

Cloudy eyes – Over time, cats can develop nuclear sclerosis, causing their eyes to take on a cloudy, grayish-blue appearance. This is a normal change, but keep an eye out for excessive tearing, discharge or redness as well (Great Pet Care, 2022).

Increased vocalization – Senior cats may meow more frequently due to disorientation, anxiety, or cognitive issues. Excessive meowing, especially at night, can signal dementia in elderly cats (Great Pet Care).

Bad breath – Dental issues like gingivitis and tooth loss often cause bad breath in aging cats. Schedule regular dental cleanings with your vet (Great Pet Care).

Changes in temperament – Personality changes like increased reclusiveness or neediness can indicate aging. Older cats may act more anxious or stressed. Monitor changes closely and discuss any major shifts with your vet (Great Pet Care).

Caring for Senior Cats

As cats age, their needs change and they require specialized care to keep them healthy and happy. Here are some tips for caring for your senior cat:

Meet their medical needs. Take your senior cat to the veterinarian for regular checkups and lab work. Senior cats are prone to diseases like kidney disease, hyperthyroidism, arthritis, cancer and cognitive dysfunction. Getting regular veterinary care can help catch issues early.

Adjust their diet. Feed senior cats a high quality diet formulated for mature cats, which has increased protein and is highly digestible. Wet food can also help senior cats stay hydrated. Obesity is a problem in many older cats, so watch your cat’s calorie intake.

Keep their mind active. Senior cats benefit from continued environmental enrichment and mental stimulation. Provide puzzle feeders, new toys, cat trees and windows with views to keep their mind engaged.

Accommodate limited mobility. Place litter boxes, food and water on the same level your cat spends most time. Add ramps or steps to help them access their favorite nap spots. Regular, gentle exercise like short play sessions helps joint health.

Give tender loving care. Spend time petting, brushing and interacting with your senior cat. Monitor their behavior and comfort levels. Keep their bed soft and warm. Your companionship helps enrich their golden years.

With attentive care focused on their changing needs, you can keep your senior cat content and healthy well into their twilight years.
