National Zoo Staff have determined that the genetically valuable litter of two
clouded leopard cubs born at the Smithsonian Conservation Biology
Institute in Front Royal, Va. Feb. 14 (Valentine’s Day) are both male.
The cubs are now eating up to 88 grams of feline diet, two times per
day, in addition to formula. The cubs are growing at a steady and
healthy rate—the larger cub weighs 4 pounds and 9 ounces and the smaller
cub weighs 4 pounds and 7 ounces. In addition, the cubs now ‘chuff,’
which can be described as a puffing sound and is considered a sign of
recognition. They are very playful—rolling around and chasing each
other—after each feeding.
