Research overview: feline obesity and its health consequences

Obesity has become one of the most common nutritional disorders in domestic cats, driven by overfeeding, calorie-dense diets, indoor sedentary lifestyles, and neutering, and it substantially increases the risk of diabetes mellitus, hepatic lipidosis, osteoarthritis, and reduced lifespan. Managing feline obesity requires controlled weight loss to avoid dangerous hepatic lipidosis from rapid fasting. This overview synthesizes the nutrition and clinical literature rather than one citation, describing the drivers and health consequences of feline obesity, why safe gradual weight reduction is essential, and how diet, portion control, and activity are used in management. It matters because obesity underlies several major feline diseases, making its prevention and careful treatment central to feline preventive medicine and to reducing the burden of conditions like diabetes that flow from excess body weight.
