How much does the fattest cat in the world weigh? - in detail
The weight of the fattest cat in the world is a subject of considerable interest and curiosity among animal enthusiasts and the general public. As of the current data available in 2025, the heaviest cat ever recorded was a Maine Coon named Barivel. Barivel, an Italian cat, achieved notoriety in 2016 when he was officially recognized by the Guinness World Records as the heaviest cat, weighing in at a staggering 30.6 kilograms (67.5 pounds).
Several factors contribute to a cat reaching such an extraordinary weight. Genetics play a significant part, as Maine Coons are naturally one of the largest domestic cat breeds. Their robust build and tendency to grow larger than other breeds make them more susceptible to becoming overweight if not properly managed. Additionally, diet and lifestyle are crucial elements. Overfeeding, lack of exercise, and a diet high in calories can lead to rapid weight gain. In Barivel's case, his owners reportedly fed him a diet rich in protein and fats, which, combined with his genetic predisposition, resulted in his substantial size.
It is essential to note that while Barivel's weight is impressive, it is not necessarily healthy. Obesity in cats can lead to a variety of health issues, including diabetes, heart disease, and joint problems. Veterinarians and animal welfare organizations often emphasize the importance of maintaining a balanced diet and regular exercise for pets to ensure their overall well-being.
In summary, the fattest cat in the world, Barivel, weighed 30.6 kilograms (67.5 pounds) at his heaviest. This remarkable weight is a result of a combination of genetic factors, diet, and lifestyle. However, it is crucial to recognize that such extreme weight is not indicative of good health and that responsible pet ownership involves ensuring a cat's diet and activity levels support a healthy weight.
