THURMONT, Md. - Two jaguar cubs born at the Catoctin Wildlife Preserve and Zoo earlier this month can already walk, although with a "wobble," and are developing personalities, zoo employees said Thursday.
The first cub, born Feb. 10, was a spotted female. The second cub, born Feb. 12, was a black male.
It is unusual for jaguar cubs to be born more than 24 hours apart, Zoo Communications Director Whitney Hahn said.
"We were not expecting the second one," she said.
The male weighs about five pounds, the female about 4 1/2 pounds, Bette Jorden, mammal curator and primary caretaker for big cats, said.
Jaguars are endangered in their tropical South American habitats and are rare even in American zoos, Hahn said. Unlike lions and tigers, jaguars are difficult to breed in captivity, she said.
