I love cheetahs. They are actually surprisingly docile for their size and have on a few occasions in history even flirted with domestication. Not suggesting we should domesticate them but still, it's a pretty neat fact!
I met a 'domesticated' one outside a 'snake park' in Kenya. It was chained up but seemed quite contented and approachable. It purred like a house cat when I stroked it behind the ears. It's quite clear that they can be 'domesticated'.
