IN the current economic climate, many people are making drastic (巨大的) career changes. It seems our friends in the animal kingdom have hit hard times too – at least for one rabbit on a small sheep farm in Sweden, who has taken up sheep-herding (牧羊). This is usually a dog’s job. “He learned these skills himself. We had nothing to do with it,” Greta Vigren, the rabbit’s owner, told a local website. The owners suspect the rabbit learned to herd the sheep by watching local dogs. A video of the hopping (蹦跳的) herder has been extremely popular on YouTube recently.
