Cats are among the world’s most beloved pets, with their global population estimated to exceed one billion in 2025. Beyond companionship, research suggests that living with a cat may offer significant health and emotional benefits.
According to global estimates, more than 350 million cats live as pets, while nearly 480 million are strays. Countries with the largest cat populations include the United States, China, Russia, Brazil and the United Kingdom.
Cats help reduce stress and boost well-being
Research led by Professor Takefumi Kikusui of Japan’s Azabu University found that interaction between pet owners and their cats can trigger the release of oxytocin, often referred to as the “love hormone”.
The study observed that after 30 minutes of mutual gazing, oxytocin levels increased significantly in both cats and their owners. The hormone is associated with feelings of trust, bonding, relaxation and emotional well-being.
Experts say petting and interacting with cats may help reduce stress, ease anxiety and promote a sense of calm.
Study links cat ownership to heart health
A long-term study conducted by researchers at the University of Minnesota found that cat owners had a lower risk of dying from heart attacks compared to people who did not own cats.
The 10-year study, which tracked more than 4,000 individuals, reported that cat owners experienced a 30 per cent lower risk of heart attack-related death.
Researchers believe reduced stress levels may partly explain the association, although they noted that lifestyle and personality traits common among cat owners could also contribute to the findings.
Cats continue to win hearts worldwide
Cats remain particularly popular in countries such as Japan and Russia, where they outnumber pet dogs. Their independent nature, relatively low maintenance and affectionate companionship have made them a favourite choice for millions of households.
While experts caution that owning a cat alone is not a guarantee of better health, growing evidence suggests that the companionship of a feline friend may contribute positively to both mental and physical well-being.
As cat ownership continues to rise globally, these furry companions are proving to be more than just pets—they may also be valuable partners in leading a healthier and happier life.
