Burmese cats are energetic, outgoing, and excessively keen on grooming, in line with some analysis. They might even be one of many cat breeds that stay the longest.
Most cat breeds are lower than 150 years previous, and there is not a whole lot of info on how variations between the varied varieties have an effect on their lifespans.
To assist change that, a current examine in contrast 12 frequent cat breeds to find out which of them stay the longest.
Studying extra in regards to the completely different breeds will enable cat homeowners “to foretell the long run life expectancy for his or her cats based mostly on novel scientific strategies and the facility of huge knowledge,” stated examine co-author and veterinarian Dan O’Neill in a assertion.
The researchers discovered Burmese and Birmans stay the longest, with a median of 14 years, about two years longer than the typical cat. However why these breeds outlive their friends is not clear.

For this current examine, researchers from London’s Royal Veterinary Faculty (RVC) and the Nationwide Chung Hsing College in Taiwan appeared on the ages of seven,936 cats who died between 2019 and 2021.
Over 7,000 of the cats within the examine have been combined breeds. A lot of the different 11 breeds included breeds like British cats, Maine Coons, Ragdolls, and Persians.
Usually, cats’ life expectations ranged from about 9 to 14 years, the researchers discovered.
For instance, siamese and mixed-breed cats’ life expectations have been over 11.5 years, whereas others — Norwegian Forest, Maine Coon, Russian, and British — have been over 9.5 years.
This is a desk of what the researchers discovered:
*Some breeds, like Sphynx cats, might not have had sufficient knowledge to precisely mirror lifespans, stated Leslie Lyons, who research home cat genetics on the College of Missouri.
Whereas the researchers’ findings did point out Burmese and Birmans lived longest, virtually each breed had a minimum of one cat that lived to be over 20 years previous.
Limitations with the info
One potential difficulty with among the knowledge is that it may be tough for individuals to know their cats’ breeds, Lyons stated.
“A few of these cats listed as a selected breed may probably not be what we might name a pedigreed breed,” she stated. An proprietor might assume their shelter cat with silvery fur is a Russian Blue, for instance, when it is truly a combined breed.
In contrast to canines — a few of which have been used for a whole bunch of years to hunt, corral sheep, or pull sleds — cats have been usually bred for aesthetic causes relatively than persona or athleticism.
That is why breed variations aren’t as dramatic in cats as they’re in canines and may not affect cats’ well being in the identical manner.
It isn’t like evaluating a Doberman to a Pekingese. That is as a result of cats’ aesthetic traits are genetically much less complicated than canines’ behavioral and purposeful ones, Lyons stated.
Nevertheless, these breed preferences can nonetheless have unintended penalties, like Persian cats’ brief noses, which may trigger respiratory difficulties.
How lengthy a cat lives relies on loads of components

Along with breed, the examine checked out a variety of components, like intercourse, weight, and whether or not the cat was spayed or neutered. Females and stuck cats each tended to stay a bit longer.
Lyons sees this examine as a jumping-off level for additional investigations into components that affect life expectations like time spent indoors or outside, which the examine did not account for.
Automobile accidents, parasites, and fights with different felines are only a few of the hazards for cats who enterprise outdoors. Consequently, some analysis suggests out of doors cats have a median lifespan of solely two to 5 years.
The authors, who revealed their examine within the peer-reviewed “Journal of Feline Drugs and Surgical procedure,” stated additional analysis is required into the causes of dying in companion cats, together with within the Sphynx breed.
