I visited the Tenikwa Wildlife Rehabilitation Centre (http://www.tenikwa.com/) in the South African Western Cape. The cheetahs have become so accustomed to their carers - here is one taking a selfie with her feeder! When asked about their relationship he said "She doesn't like me, she likes my hands because they smell like her food - she was licking them just before" I like to think she likes him a little bit.
