Feline obesity is the most common preventable health problem in companion cats, causing diabetes, joint pain, hepatic lipidosis risk, and reduced life expectancy.
Feline obesity is a welfare problem on multiple levels: the obese state itself causes pain (joint disease), metabolic dysfunction (diabetes), and impaired mobility that reduces quality of life; and it predisposes to life-threatening conditions. Owner perception of cat body condition is poor — studies show owners consistently underestimate overweight cats. Weight management requires a structured, gradual approach: rapid calorie restriction in cats causes hepatic lipidosis, a potentially fatal condition. Veterinary guidance on target weight, rate of loss (1-2% body weight per week maximum), and diet selection is essential. Puzzle feeders and increased activity prevent boredom-related overeating and support weight loss. Regular body condition scoring using standardised charts provides objective monitoring.
