Do Smaller Cats Live Longer?

It is scientifically proved that smaller cats with lower weight tend to live longer than those healthy and bulky cats. This is due to following reasons:

  • Lower metabolic rate: Smaller cats generally have slower metabolic rates compared to larger cats. A slower metabolism can lead to less wear and tear on the body over time, potentially contributing to a longer lifespan.
  • Reduced strain on organs: Smaller cats have less body mass, which means their internal organs don’t have to work as hard to support them. This reduced strain on organs like the heart and kidneys can result in better overall health and longevity.
  • Lower risk of obesity: Smaller cats require fewer calories than larger cats to maintain their weight. This lower caloric requirement, combined with their smaller size, makes them less prone to obesity, which is a significant risk factor for many health problems in cats, including diabetes, arthritis, and heart disease.
  • Genetic factors: Some smaller cat breeds have been selectively bred for their longevity and overall health. Breeders often prioritize breeding for traits associated with a longer lifespan, such as robust health and vitality.
