Read this excerpt from Rikki-Tikki-Tavi by Rudyard Kipling. He was a mongoose, rather like a little cat in his fur and his tail, but quite like a weasel in his head and his habits. His eyes and the end of his restless nose were pink; he could scratch himself anywhere he pleased, with any leg, front or back, that he chose to use; he could fluff up his tail till it looked like a bottle-brush, and his war-cry, as he scuttled through the long grass, was: "Rikk-tikk-tikki-tikki-tchk!"
