It is the silly season … and after achieving worldwide fame by teaching his pet mice to surf, Shane Willmott, who lives on Australia's Gold Coast, has now trained them to ride skateboards. He decided to teach them to skateboard because it was too cold in winter to take them to the beach. "They love it," he said. "Mice are built to surf and skate because their centre of gravity is so low. When they do fall off, they want to get straight back on board." Photograph: Tim Marsden/Newspix/Rex
