The world's first mini-mule a horse crossed with a miniature Shetland pony

Meet the world's first mini-mule - a miniature Shetland pony crossed with donkey which has left vets baffled and is already nearly the same size as its mum. Lauren Mosgrove, 24, homed 30-inch pony Peaches in a field with Donk the donkey, who measured 53 inches. Vets assured her it was impossible for the animals to breed due to their size difference, so she was stunned when Peaches, 11, gave birth to a donkey-mini horse cross last week. Lauren, from Jedburgh in the Scottish Borders, reckons new arrival Katie is the only only animal of its kind in the world.
