A goat sent to a Russian safari park as live prey for a Siberian tiger has instead befriended the big cat and the two have become inseparable in a story that has captivated Russians. Amur the tiger and Timur the goat now sleep in the same enclosure in the Primorsky safari park outside the Pacific port city of Vladivostok, and the pair eat and play together in the snow and this week even head-butted each other for fun.
