Feline obesity requires careful, gradual weight reduction with veterinary oversight, as rapid weight loss in cats triggers life-threatening hepatic lipidosis rather than improving health.
Feline weight loss welfare requires balancing the long-term welfare benefits of reaching healthy weight against the short-term welfare risks of inappropriate restriction. The hepatic lipidosis risk means that well-intentioned aggressive restriction can cause a welfare emergency more severe than the obesity being treated. Cats that refuse to eat their new diet and owners who then capitulate and return to previous feeding perpetuate the cycle of obesity without resolution. The challenge is that cats are behaviorally resistant to diet changes and may go on food strikes when their preferred diet is removed. A slow, thoughtful transition with veterinary support, appropriate caloric targets calculated for the individual cat's resting energy requirement, and owner support for the process improves compliance and reduces risk. Environmental enrichment that promotes activity complements dietary management.
