As a relentless summer heat wave transforms Korea’s urban concrete into open-air saunas, human residents typically retreat toward air-conditioned cafes and iced Americanos. But for the roughly 100 species residing at Seoul Grand Park, surviving August requires a vastly different culinary strategy: frozen beef leg bones, whole watermelons, and the high-stakes thrill of hunting live catfish. Zoo officials at the park dispatched a staggering 920 kilograms of specialized seasonal treats across 15 animal enclosures, Friday, launching an annual summer welfare campaign designed to combat heat-induced apathy, dehydration, and thermal stress. For the park's apex predators, cooling down is a deeply carnivorous affair. Siberian tigers, whose natural evolutionary blueprint leans toward frigid Russian taigas rather than muggy Korean summers, received electrolyte-rich ice cakes packed with raw chicken, calcium-dense beef leg bones, and fresh meats. The frozen blocks double as thermal regulation and behavioral enrichment, requiring the big cats to lick, chew, and claw their way to a protein-rich pay
