Cat Overweight and Obesity Welfare

Feline obesity is a widespread welfare crisis affecting an estimated 40-50% of domestic cats, causing chronic disease and reduced quality of life.

Key Facts

An estimated 40-50% of domestic cats in developed countries are overweight or obese by veterinary body condition standards.
Obese cats have significantly higher rates of diabetes, hepatic lipidosis, osteoarthritis, lower urinary tract disease, and skin problems.
Indoor-only cats on unrestricted dry food diets are at highest obesity risk — they cannot self-regulate calorie intake on energy-dense foods.
Even modest weight loss (1-2 kg) produces measurable improvements in mobility, grooming ability, and quality of life in obese cats.
Cats are strict carnivores with protein-focused metabolisms poorly suited to high-carbohydrate dry food diets.

Welfare Considerations

Feline obesity causes chronic, multi-system welfare compromise that progresses silently for years before obvious clinical signs appear. An obese cat has impaired mobility, difficulty grooming rear quarters, reduced play capacity, and is physiologically vulnerable to a cascade of diseases. The welfare tragedy is that obesity is largely preventable and reversible — appropriate portion control, species-appropriate diet composition, and environmental enrichment that encourages movement are effective interventions available to every owner.

What You Can Do

Have your vet assess your cat's body condition score annually and seek dietary advice if overweight.
Measure food portions by weight rather than feeding ad libitum from a bowl.
Introduce puzzle feeders that make cats work for their food — slowing eating and encouraging activity.
Transition overweight cats to wet food which has lower caloric density and higher protein than most dry foods.
