Cat
The domestic cat provides zero nutritional value under normal circumstances of human-feline cohabitation. Whilst technically composed of proteins and fats that could sustain human metabolism, the consumption of companion animals remains culturally prohibited across the majority of the cat's global range. The cat instead functions as a nutritional liability, consuming resources rather than providing them.
A standard adult cat requires approximately 200 to 300 calories daily, drawn entirely from the household food budget. Over a typical fifteen-year lifespan, this represents a nutritional deficit of roughly 1.2 million calories. The cat contributes nothing to this balance sheet except occasional gifts of partially consumed rodents, which remain culinarily unsuitable by any reasonable standard.
Rice
Rice delivers nutritional value with industrial efficiency. A single cup of cooked white rice provides 206 calories, 4.3 grams of protein, and negligible fat, representing an optimal fuel source for human metabolic requirements. The grain has sustained civilisations, fuelled armies, and enabled population densities impossible under alternative agricultural regimes.
Beyond mere calories, rice serves as a delivery mechanism for complementary nutrients. Paired with legumes, it provides complete protein profiles. Fortified varieties address micronutrient deficiencies across developing nations. The grain's nutritional versatility has prevented more famines than any single food source in human history, a contribution no feline can approximate.
