Obesity is the most common nutritional problem in cats, causing chronic disease and reduced quality of life that requires proactive management.
Obesity in cats causes chronic pain from arthritis, difficulty with normal activities including grooming and litter box use, and substantially shortened lifespan. Obese cats cannot clean themselves properly, leading to skin problems and reduced behavioral welfare. Owner tendency to equate food with love leads to overfeeding that harms the cat. A vet-guided weight loss program that protects cat welfare through safe slow loss while maintaining quality of life is the welfare-appropriate response.
