Average Lifespan
According to a recent study, the average remaining life expectancy of cats after their first year is 11.7 years.
Study Methodology
Researchers from the Royal Veterinary College (RVC) in the UK and the National Chung Hsing University in Taiwan analyzed data from 7,936 cats registered with veterinary practices in the UK that had died between January 1, 2019, and March 31, 2021, to calculate their expected life expectancy.
Key Findings
Gender Differences
Overall, female cats were found to live longer (12.5 years) than male cats (11.2 years).
Breed Variations
- Sphynx: Had the shortest life expectancy at 6.7 years after the first year, possibly due to their increased susceptibility to various health conditions.
- Burmese and Birman: Could live over 14 years.
- Siamese: Could live over 11.7 years.
- Bengal: Could live over 8.5 years.
Crossbreeds vs. Purebreds
The study found that crossbreeds (which accounted for 88% of cats) had longer lifespans than purebreds, with an average remaining lifespan after the first year of 11.9 years compared to 10.4 years for purebreds.
Expert Insights
Professor Dan O'Neill, co-author of the study and an epidemiologist at the RVC, highlighted the significant difference in lifespan between genders and breeds. He said that if owners want their cats to live a little longer, "this study now provides them with evidence that perhaps owning a female, crossbreed cat might be a route to consider."
Other Factors Influencing Lifespan
- Non-neutered cats had shorter lifespans.
- Cats with an average weight lived longer than those that were underweight or overweight.
Significance of Findings
O'Neill emphasized that the study provides cat owners with a tool to understand and predict their cats' future lifespans. This information is also valuable for potential owners, welfare organizations, and veterinarians.
Additionally, the findings can help inform decisions about whether to invest in potentially expensive and invasive medical treatments and surgeries for cats approaching the end of their expected lifespan.
Summary
- Female cats have a longer life expectancy than male cats.
- Crossbreed cats tend to live longer than purebred cats.
- The Sphynx has the shortest life expectancy among popular breeds, while Burmese and Birman cats have the longest.
- Neutering and maintaining a healthy weight can contribute to a longer lifespan.
- The study provides valuable insights into cat lifespan and can guide decisions related to pet ownership and healthcare.
