Video: One-day-old clouded leopard cubs at the Smithsonian’s National Zoo Conservation and Research Center

One-day-old clouded leopard cubs at the Smithsonian’s National Zoo Conservation and Research Center, originally uploaded by Smithsonian’s National Zoo.

An endangered clouded leopard at the Smithsonian’s National Zoo’s Conservation and Research Center (CRC) in Front Royal, Va., gave birth to a genetically valuable litter of two cubs on Tuesday, March 24. Staff had been on pregnancy watch of the two-and-a-half year-old clouded leopard “Jao Chu” (JOW-chew) for five days. She gave birth to the litter early Tuesday morning.

This is Jao Chu’s first litter. She and the cubs’ father, two-and-a-half year-old “Hannibal,” were born in Thailand in a collaborative research program with the Zoological Park Organization of Thailand. The cubs’ sex will not be known until the first veterinary exam.

Due to deforestation and hunting, clouded leopards are vulnerable to extinction. National Zoo scientist Dr. JoGayle Howard and colleagues are aggressively working toward saving this species from decline. The Zoo has been working with clouded leopards at the Conservation & Research Center since 1978, with the goal of creating a genetically diverse population. In the past 30 years, more than 70 clouded leopards have been born at the Zoo’s research facility in Virginia, with the last litter born in 1993.

Breeding clouded leopards in captivity has been a challenge, primarily due to male aggression, decreased breeding activity between paired animals, and high cub mortality. In 2002, the National Zoo in collaboration with the Nashville Zoo and the Clouded Leopard Species Survival Plan (SSP) created the Thailand Clouded Leopard Consortium—the largest population of confiscated clouded leopards in Southeast Asia. The Clouded Leopard SSP oversees clouded leopard populations in zoos worldwide, and makes breeding recommendations for potential pairs based on the genetics of each cat. Since Thailand’s captive cubs are only one or two generations removed from the wild, their genes are especially valuable.

To date, the Thailand Clouded Leopard Consortium has produced 32 surviving cubs. The National Zoo’s program at the Front Royal facility is the only one of its kind combining breeding with scientific research. For example, scientists still do not know why male clouded leopards attack their possible mates, but several graduate students at the National Zoo are studying the males’ behavior—one student plans to test anti-anxiety drugs used in humans and domestic cats in an attempt to suppress male aggression.

Howard and colleagues have learned how to reduce the risk of fatal attacks by hand-rearing cubs for socialization and also introducing males to their mates when they are six months old, allowing the pair to grow up together. Hannibal and Jao Chu, the only compatible pair of clouded leopards at CRC, are proof that these techniques work. The new cubs also will be handreared by experienced CRC staff.

Following mating, the gestation period for clouded leopards is about 86 to 93 days. The average litter size for clouded leopards is two to five cubs. Clouded leopard cubs weigh about a half of a pound when born.

Little is known about clouded leopards. They are cats native to Southeast Asia and parts of China in a habitat that ranges from dense tropical evergreen forests to drier forests if there is suitable prey.

They are the smallest of the big cats, weighing 30 to 50 pounds and measuring about five feet long. Their short legs, large paws, and long tail (accounts for half their length) help them balance on small branches, and their flexible ankles allow them to run down trees headfirst.

The newborn cubs will not be on exhibit at CRC. However, visitors may get an up-close treetop view of two clouded leopards—a male named Tai and a female named Mook—at Asia Trail at the National Zoo’s campus in Washington, D.C.
