To uncover the average lifespan of various cat breeds and identify the factors influencing their longevity, researchers examined data from approximately 8,000 cats across the United Kingdom. A team of pathobiologists from the Royal Veterinary College (UK) and Chung Hsing University (Taiwan) discovered that Burmese cats tend to live the longest, while Sphynx cats have the shortest lifespan.
What the Researchers Found
The researchers gathered data on 7,936 domestic cats that passed away in the UK between January 2019 and March 2021. While the average lifespan of a cat breed can be a useful indicator, it doesn’t provide the full picture. To gain a clearer understanding of the expected lifespan of these animals, the researchers developed what are known as mortality tables. This allowed the team to determine the average life expectancy of cats, as reported by Live Science.
The study revealed that domestic cats live an average of 11.7 years. Mixed-breed cats, on average, live about 1.5 years longer than purebred cats. Burmese cats outlive other breeds, averaging around 14.4 years, while Sphynx cats have a significantly shorter lifespan of just 6.7 years—likely due to their genetic predisposition to heart, eye, and muscle diseases.
The researchers also identified other factors, aside from breed, that affect the lifespan of our furry companions. Female cats tend to live, on average, 1.3 years longer than males. Additionally, spayed and neutered pets live about 1.1 years longer than those that are intact. Another influencing factor is lifestyle, particularly whether cats are kept indoors or allowed outside. Outdoor cats are more frequently exposed to various external dangers that can hinder their longevity.
Mortality tables are beneficial for both veterinarians and prospective cat owners, as they contain crucial information to consider when making important decisions regarding cat adoption, treatment, or euthanasia. This point was emphasized by study co-author Candy Ten, an epidemiologist specializing in small animals. The research also had an unexpected emotional impact on some cat owners. According to Ms. Ten, after the results circulated on social media, the scientists received a flood of sentimental comments. Many were touched by the realization that their beloved cats might not have much time left. “I need to treat my cats better or cherish the time we have together,” wrote some pet owners. As a result, they inadvertently began to appreciate the time spent with their cats, eager to strengthen their bond and improve their care. The findings of this study were published in the journal Feline Medicine and Surgery.
