An average neutered indoor cat needs only ~200 kcal/day — roughly two-thirds of a standard kibble cup, which is why free-feeding drives the feline obesity epidemic (~60% of cats). Cats are obligate carnivores with low thirst drive: wet food helps hydration and weight control. Never crash-diet a cat — rapid weight loss risks hepatic lipidosis, a deadly liver condition. Vet-supervised loss only.
