Primate mum: Anjana the chimp helps zookeepers to care for orphaned puma cub, Sierra
The chimpanzee, who is five, has lived her whole life at The Institute of Greatly Endangered and Rare Species (TIGERS) in South Carolina, in the U.S.. She learned to care for little big cats while in the charge of resident feline curator China York. Park director Dr Bhagavan Antle said: 'Chimpanzees are great learners and imitators so it wasn't long before she took on the right behaviours that were necessary to keep the kittens in line.

'If Sierra is running around too fast then Anjana will scoop her up and make sure she doesn't get into any trouble.'Anjana has already helped to bring up two royal white tiger cubs, a leopard and four lions.Dr Antle added: 'She is a great assistant. If you need a baby wipe you can just tell her and she'll run off and get it.'
