The average lifespan of domestic cats is 12–18 years, while in dogs this figure is often lower. Scientists decided to find out the reasons for such a difference and came to unexpected conclusions. It turns out that both body size and evolutionary features have a significant impact.

The lifespan of animals depends on many factors: genetics, lifestyle, diet, and even the evolutionary characteristics of the species. Researchers have found that the secret to cats’ longevity may be linked not only to their habits but also to the peculiarities of their immune system and body structure.
Why cats live longer than dogs: scientists explain the main reasons
-
The role of evolution and lifestyle. Scientists cite the evolutionary development of cats as one of the main reasons for their longer lives. They are innate loners and hunters who less often enter into conflicts with other animals and risk serious injuries less. Dogs, historically, have been more social animals, and many breeds were developed by humans for specific tasks – hunting, guarding, or herding livestock. This has influenced their physiology and health.
-
Big body – shorter life. Studies show that among dogs, large breeds generally live shorter lives than small ones. Scientists attribute this to faster growth rates and greater strain on the heart, joints, and other systems. Cats have more stable body sizes, which may positively affect aging processes and lifespan.
-
The immune system matters. Scientists also pay attention to immune system peculiarities. Some studies suggest that species with more complex immune systems may better resist infections and age-related diseases. This is why cats often maintain activity and good health for longer, even at an advanced age.
How to extend your pet’s life
Regardless of the animal species, its longevity largely depends on care. Veterinarians recommend:
-
providing a balanced diet;
-
regular preventive check-ups;
-
adhering to the vaccination schedule;
-
maintaining physical activity;
-
monitoring the pet’s weight.
Pets that receive proper care often live longer and encounter serious illnesses less frequently.
