A long time ago, the Lion, the Fox, the Jackal, and the Wolf agreed to go hunting together, sharing with each other whatever they found. But he forgot to latch the door of his house and while he was gone a Weasel walked in and calmly made himself at home. One day he heard that some Birds in the neighborhood were ailing and needed a doctor. The moment he caught sight of me he opened his pointed mouth as if to swallow me, and then he let out a piercing roar that frightened me almost to death. Come close to me, said the Cat, I am very deaf. That means me, I suppose. There they left him to mourn the foolishness that had brought him nothing but a sound beating.
A change of habits will not alter nature.
