The eight-week-old clouded leopard cubs born at the Smithsonian National Zoo’s Conservation and Research Center (CRC) are now eating solid food in addition to formula. Their diet includes 8 grams of cooked chopped chicken, three times per day.

The cubs are growing at a steady and healthy rate—the larger cub weighs 3 lb. and 3.5 oz. and the smaller cub weighs 2 lb. and 12 oz. Additionally, the cubs now ‘chuff’, which can be described as a puffing sound and is considered a sign of recognition. The length of their play sessions has increased and they interact more with their caregivers.
