Companion Animal Welfare

Companion Cat: Obesity Assessment and Treatment

Feline obesity is extremely common and causes significant welfare harm through joint pain, diabetes risk, and reduced quality of life.

Key Facts

Studies estimate 40-50% of pet cats in developed countries are overweight or obese
Obesity in cats causes degenerative joint disease, diabetes mellitus, and urinary tract problems
Neutering increases metabolic rate reduction by approximately 20%, increasing obesity risk
Body condition scoring using palpation of the ribs is the most practical assessment tool
Gradual weight loss over 4-6 months is safer than rapid weight loss which risks hepatic lipidosis

Welfare Considerations

Feline obesity causes chronic pain through joint loading, metabolic disease, and reduced mobility that impairs quality of life. Obese cats often cannot groom effectively, creating secondary skin and hygiene problems. The insidious nature of obesity - developing gradually over years - means owners normalise their cat's weight before intervention. Regular body condition scoring at every veterinary visit catches progressive weight gain before it becomes severe.

What You Can Do

Learn to body condition score your cat using the 9-point scale
Schedule annual weight checks with your vet and earlier if your cat gains weight
Feed measured portions using kitchen scales rather than estimating by eye
Provide environmental enrichment that encourages activity
Discuss a veterinary weight loss programme if your cat is significantly overweight
