Feline obesity significantly increases risk of multiple serious conditions including diabetes, arthritis, and respiratory compromise that compound welfare harms across the lifespan.
Feline obesity creates a cascade of welfare harms that compound over time. A moderately overweight cat that develops diabetes faces insulin injections twice daily, dietary restriction, and periodic hypoglycaemic crises. The same cat with concurrent arthritis experiences joint pain that reduced grooming and play. Skin fold dermatitis from inability to groom creates painful infected folds. Each comorbidity reduces quality of life independently; together they create a significantly compromised existence. Prevention of obesity through appropriate portion control from kittenhood is far more effective and less costly in welfare terms than managing the cascade of complications once established.
