Feline Obesity: A Welfare Epidemic in Pet Cats

Welfare guide to obesity in cats -- now affecting over 40% of pet cats with significant welfare consequences.

Key Facts

Obesity now affects an estimated 40-60% of pet cats in developed countries
Obese cats have reduced lifespan, reduced quality of life, and higher risk of diabetes, arthritis and urinary disease
The primary cause is energy imbalance -- too many calories and insufficient physical activity
Ad libitum dry food feeding is a major contributing factor -- cats cannot self-regulate intake on energy-dense foods
Weight loss in cats must be gradual -- rapid weight loss causes hepatic lipidosis, a life-threatening liver condition
Interactive feeding using puzzle feeders increases activity and reduces boredom eating
Environmental enrichment providing climbing opportunities and play stimulation supports healthy weight
Regular weighing and body condition scoring enables early intervention before obesity is severe

Welfare Significance

Obesity is a growing welfare crisis in companion cats. The reduced mobility, chronic joint pain, increased disease risk, and shortened lifespan of obese cats represent significant welfare burdens that are entirely preventable. Empowering owners with evidence-based advice on diet and feeding management is the most important welfare intervention.

What You Can Do

Measure and weigh food portions rather than free-feeding
Use puzzle feeders to slow eating and encourage natural hunting behaviour
Weigh your cat monthly and record body condition score
Ask your vet for a structured weight loss plan if your cat is already obese -- do not crash diet
