Obesity affects an estimated 40-50% of adult cats and causes or worsens diabetes, arthritis, hepatic lipidosis, and urinary tract disease, with prevention far easier than treatment.
Key Facts
Cat obesity is defined as bodyweight more than 20% above ideal
Neutering reduces metabolic rate by approximately 30%, requiring dietary adjustment
Most cats control intake poorly when fed ad libitum and benefit from measured meals
Slow-feeder puzzle bowls increase feeding time and reduce rapid over-eating
Weight loss in cats must be gradual to prevent hepatic lipidosis from fat mobilisation
Welfare Considerations
Obesity causes chronic disease burden that reduces quality and length of life. Prevention through appropriate portion control from kittenhood is far preferable to managing established obesity.
What You Can Do
Feed measured portions rather than ad libitum to prevent obesity
Switch to lower-calorie food after neutering to account for reduced metabolic rate
Use body condition scoring to monitor weight status objectively
Work with your vet on a safe, gradual weight loss programme for overweight cats
