When the man was disgraced and told to go away, he was allowed to ask all the animals whether any of them would come with him and share his fortunes and his life. There were only two who agreed to come entirely of their own accord, and they were the dog and the cat. And ever since then, those two have been jealous of each other, and each is for ever trying to make man choose which one he likes best. Every man prefers one or the other.
