At five weeks old, the Cheetah cubs, whose sex has not yet been determined, are already the size of domestic cats and tip the scales at around nine pounds (4 kg). The triplets also have roly-poly milk tummies.

“All three young animals are developing splendidly.  Two of the babies come out several times a day, the third one is a bit more timid and prefers to wait in the litter cave until his mother and siblings come back,” explains the zoo’s director, Dagmar Schratter.

Baby Cheetahs grow very quickly. Schratter says, “Cheetahs are pure carnivores, but up to now the young are being suckled, although they have already broken their milk teeth. Before long, the little feline predators will be enjoying their first meal of meat.”

Once hunted for their fur, Cheetahs are listed as Endangered by the International Union for Conservation of Nature due to habitat destruction and the lack of prey. Only around 10,000 of these animals still live in Africa. The Schönbrunn Zoo participates in the European Endangered Species Programme (EEP), despite the difficulty of breeding Cheetahs in a zoo setting.  The new triplets are the first Cheetahs born at the zoo in 13 years.
