We all wish our furbabies could live forever, but have you ever thought about why cats live longer than dogs? Both are domesticated animals, but the gap between the lifespans is interesting. Dr Steve Austad, a lion trainer turned biologist, said: "There is an evolutionary theory of aging... that suggests that things live longer in safe conditions. Think of cats' solitary ways. Unlike dogs, which are pack animals, they live at low density and that tends to prevent them from catching infectious diseases."
Cats have a faster metabolic rate than dogs, due to evolution and their natural predators. These characteristics are due to their genetic diversity, cats are more resilient to disease and environmental issues, unlike dogs. Another genetic issue with dogs is many of them are inbred which leads to more genetic disorders. A lower risk of genetic disorders equals a longer lifespan.
In the past years, veterinarian advancements have given cats a longer lifespan due to the new treatments, and ranges of conditions they can treat. They have improved on many surgical techniques, and therapy treatments as well. Also as a pet owner, it is important that you know your pet and make sure there is a good relationship between you and their veterinarian so you can help better your animal's life and live a longer healthier life.
