The bouncing and bounding sisters were both born on May 16, weighing 4.5 kilograms and 4.7 kilograms (9.9 and 10.3 pounds) respectively. They are children of 9-year-old leopards, the female Kira and the male Himal, who came to the zoo at the end of last year. /VCG Photo.

They are doing well in their new environment, exploring it by their mother’s side. They will not be on exhibit the entire day before getting fully used to their new environment. /VCG Photo.

The snow leopard has thick, cream-colored coats and gray-black spots. These unique patterns act as camouflage for them in snow-covered mountainous areas, winning them the name “ghosts of the mountains.” /VCG Photo.
