JUST five weeks old, these twin baby leopards are as inquisitive as they are adorable - which is how theyve made friends with a baby orang-utan. Solka and his sister Chant go to Rishi, aged one, for warm cuddles in his already long fur. The pair, both African leopards were born at The Institute of Greatly Endangered and Rare Species, in Myrtle Beach, South Carolina. They now weigh around two pounds, stand at six inches tall and measure 12 inches from tail to nose. Hand raised by carers at the institute, these two endangered cubs will grow up to be animal ambassadors at the conservation centre, where people are given extraordinarily close access to the animal kingdom. 'Solka and Chant came away from their mother, Kirean, 10, around ten days ago, said Rajani Ferrante, who gives the cubs 24 hour care. 'The babies are fed every four hours with a special formula made from vitamins, fresh yoghurt and goats milk. 'In the wild the mothers are usually very attentive for around one month, after which they leave the babies to fend for themselves. 'When born in captivity it is necessary for trainers like myself to hand raise them. 'These guys will never be going into the wild and so to form a relationship with them they need to be hand raised by us after that time. Leopard populations are declining due to hunting and degradation of their habitat and prey base, and have a 'lower risk status on the IUCN Red List of Threatened Species. Adult male leopards usually grow to 80 cm high at the shoulder and weigh around 180 pounds, while adult females are considerably smaller, weighing around 120 pounds. Daily Mail
