Cat lifespan statistics show a wide range rather than one fixed life expectancy. In a large England primary-care study, the median longevity was 14.0 years, while a Britain study reported a mean lifespan of 10.61 years. Breed, sex, neuter status, body weight, and the way deaths are recorded all affect the number a reader sees.

At a glance
The strongest general benchmark in the supplied research comes from Longevity and mortality of cats attending primary care veterinary practices in England. That study included 118,016 cats attending 90 practices in central and south-east England and randomly selected 4,009 cats with confirmed deaths. Its median overall longevity was 14.0 years, with an interquartile range of 9.0 to 17.0 years.
The median is the middle value: half of the recorded cats lived less than that age and half lived longer. The interquartile range describes the middle half of observations, so it is often more useful than quoting a single maximum. In this study, the overall recorded range was 0.0 to 26.7 years, and longevity was bimodally distributed, with peaks at years 1 and 16.
The range includes cats that died very young as well as exceptionally old cats. It should not be read as a promise that a healthy household cat will live to a particular age. The study population was drawn from veterinary practices in a defined part of England, and its measurements describe that population and study design.
| Measure | Result | Source |
|---|---|---|
| Median overall longevity | 14.0 years | Longevity and mortality of cats attending primary care veterinary practices in England |
| Middle 50% of longevities | 9.0–17.0 years | Longevity and mortality of cats attending primary care veterinary practices in England |
| Recorded overall range | 0.0–26.7 years | Longevity and mortality of cats attending primary care veterinary practices in England |
| Mean lifespan in Britain study | 10.61 years | Life expectancy of cats in Britain: moggies and mollies live longer |
| 95% confidence interval for that mean | 10.30–10.91 years | Life expectancy of cats in Britain: moggies and mollies live longer |
The England median and Britain mean are different statistics from different studies, so they should not be treated as contradictory measurements of exactly the same population. One is a median, the other a mean, and the study populations and methods differ.
How long do cats live?
The England study provides several useful ways to describe a cat’s lifespan. Crossbred cats had a median longevity of 14.0 years, with an interquartile range of 9.1 to 17.0 years. Purebred cats had a median longevity of 12.5 years, with an interquartile range of 6.1 to 16.4 years.
Across sex categories, female cats had a median longevity of 15.0 years and an interquartile range of 11.0 to 17.4 years. Male cats had a median longevity of 13.0 years, with an interquartile range of 7.6 to 16.0 years. These are population-level comparisons, not an individual prediction.
Neuter status showed another difference in the same England dataset. Neutered cats had a median longevity of 15.0 years and an interquartile range of 11.8 to 17.0 years. Non-neutered cats had a median longevity of 11.0 years, with an interquartile range of 2.13 to 16.0 years.
| Group in the England study | Median longevity | Interquartile range |
|---|---|---|
| Crossbred | 14.0 years | 9.1–17.0 years |
| Purebred | 12.5 years | 6.1–16.4 years |
| Female | 15.0 years | 11.0–17.4 years |
| Male | 13.0 years | 7.6–16.0 years |
| Neutered | 15.0 years | 11.8–17.0 years |
| Non-neutered | 11.0 years | 2.13–16.0 years |
The study’s final multivariable model estimated that crossbred cats lived 0.6 years longer than purebred cats. It also estimated that neutered female cats lived 0.6 years longer than entire female cats, while entire male cats lived 1.8 years less than entire female cats. These are model estimates from that study, not universal effects that can be applied without context.
Lifespan by breed
The England study reported different median longevities among the named breeds in its records. Birman cats had the highest listed median at 16.1 years, followed by Burmese cats at 14.3 years, Siamese cats at 14.2 years, and Persian cats at 14.1 years.
British Shorthair cats had a median longevity of 11.8 years. Maine Coon cats had a median of 11.0 years. Ragdoll cats had a median of 10.1 years, and Abyssinian cats had a median of 10.0 years. Bengal cats had the lowest listed median in this set, at 7.3 years.
The middle-half ranges also varied considerably. Siamese cats had an interquartile range of 10.8 to 19.0 years. Abyssinians had a range of 1.1 to 18.1 years, while Bengals had a range of 2.2 to 11.5 years. Birman cats had a range of 8.1 to 16.9 years, Burmese cats 10.0 to 17.0 years, and Persian cats 12.0 to 17.0 years.
| Breed | Median longevity | Interquartile range |
|---|---|---|
| Birman | 16.1 years | 8.1–16.9 years |
| Burmese | 14.3 years | 10.0–17.0 years |
| Siamese | 14.2 years | 10.8–19.0 years |
| Persian | 14.1 years | 12.0–17.0 years |
| British Shorthair | 11.8 years | 5.8–16.3 years |
| Maine Coon | 11.0 years | 4.0–15.5 years |
| Ragdoll | 10.1 years | 0.9–14.8 years |
| Abyssinian | 10.0 years | 1.1–18.1 years |
| Bengal | 7.3 years | 2.2–11.5 years |
Breed medians should be read alongside their ranges. A median summarizes a group, while the range shows how much individual outcomes varied. The data also come from veterinary practices in central and south-east England, so these figures do not establish a ranking for every cat population worldwide.
Sex and neuter status
The sex and neuter comparisons point in the same general direction in the England primary-care study: the recorded median was higher for females than males and higher for neutered cats than non-neutered cats. Female cats had a median of 15.0 years versus 13.0 years for males. Neutered cats had a median of 15.0 years versus 11.0 years for non-neutered cats.
A separate necropsy study, Longevity and mortality in cats: A single institution necropsy study of 3,108 cases, illustrates why study design matters. In that study, the median age at death for intact males was 0.79 years, with an interquartile range of 0.38 to 3.08 years. For castrated males, the median age at death was 9.55 years, with an interquartile range of 5.30 to 12.83 years.
Among cats in that necropsy study that died at or after 1 year old, intact males had a median lifespan of 3.67 years, with an interquartile range of 1.96 to 8.70 years. Male neutered cats had a median lifespan of 9.84 years. These necropsy figures describe cats represented in a single-institution necropsy population; they are not a general life table for all owned cats.
Why cats die
The England primary-care study recorded trauma as the most frequent attributed cause of mortality: 405 deaths, or 12.2%. Renal disorder accounted for 399 deaths, or 12.1%; non-specific illness for 370 deaths, or 11.2%; neoplasia for 356 deaths, or 10.8%; and mass lesion disorders for 336 deaths, or 10.2%.
Other attributed causes included neurological disorders at 231 deaths and 7.0%, respiratory disorders at 183 deaths and 5.5%, cardiac disease at 139 deaths and 4.2%, endocrine disorders at 124 deaths and 3.8%, and thromboembolic disease at 106 deaths and 3.2%.
The same study listed enteropathy at 98 deaths and 3.0%, hepatopathy at 61 deaths and 1.8%, viral disorder at 60 deaths and 1.8%, and urinary disorder at 57 deaths and 1.7%. Euthanasia accounted for 85.7% of deaths in the study, and 74.7% of the cat deaths were cremated.
The necropsy study grouped causes differently. Cancer was the most common pathophysiologic cause at 35.81% of deaths. Infectious causes accounted for 17.47%, degenerative causes for 11.97%, renal failure for 10.81%, feline infectious peritonitis for 6.72%, and cardiac disease for 5.18%. The four leading necropsy-study causes together accounted for 58.52% of all deaths.
These percentages should not be combined across the two studies. The England research used primary-care records and attributed mortality categories, while the necropsy research examined 3,108 cats at a single institution. The necropsy study also reported that the median percentage of cats undergoing necropsy each year was 4.59%, with an annual range of 1.81% to 6.16%.
Weight and other modeled differences
The England study’s final multivariable model included body-weight categories. Compared with cats under 3.0 kg, cats weighing 3.0 to 3.9 kg lived an estimated 0.8 years less. Cats weighing 4.0 to 4.9 kg lived 1.7 years less, cats weighing 5.0 to 5.9 kg lived 2.0 years less, and cats weighing at least 6.0 kg lived 3.3 years less.
The same model estimated that insured cats lived 1.1 years less than uninsured cats. This is an association in the model, not evidence that insurance shortens lifespan. Insurance status may reflect other characteristics of the cats or their care, and the supplied statistic does not establish a cause.
The weight figures also should not be interpreted as a target weight prescription. A cat’s healthy body condition depends on its individual build and health, and the study’s categories describe recorded groups rather than a universal ideal for every cat.
What “senior” means in veterinary guidance
Cornell University College of Veterinary Medicine’s feline-health guidance says cats are now often considered older at 12 to 14 years, compared with the older convention of 8 years. Cornell also notes that its oldest feline patient reached a healthy 22 years old.
Cornell says cats become adults at about 1 year of age. For geriatric care, its guidance recommends six-month checkups for geriatric cats. It also recommends a yearly geriatric exam for healthy cats, with blood work and X-rays included in that yearly exam.
Together, these figures put longevity statistics into a practical age framework: a cat can be an adult at about 1 year, enter the age range often treated as older at 12 to 14 years, and still reach the 20s. The individual outcome remains shaped by the cat’s health and circumstances, while the study medians describe patterns observed in particular research populations.
