Mbh 5.161.2b

I will here repeat to thee, O king, this excellent story recited by Narada to my father. A wicked cat, O king, once on a time took up his abode on the banks of the Ganges, abandoning all work and with his hands upraised (after the manner of a devotee). Pretending to have purified his heart, he said unto all creatures these words, for inspiring confidence in them, viz.,--I am now practising virtue. After a long time, all oviparous creatures reposed trust in him, and coming unto him all together, O monarch, they all applauded that cat. And worshipped by all feathery creatures, that devourer of feathery creatures, regarded his purpose already accomplished, as also the purpose of his austerities. And after some more time, the mice went to that place. And these also all beheld him to be a virtuous person engaged in the observance of vows, and proudly exerting himself in a grand act. And having arrived at that settled conviction, they entertained the following wish, O king,--‘Many foes we have. Let this one, therefore, become our maternal uncle, and let him always protect all the old and young ones of our race.’ And going at last to the cat, all of them said, ‘Through thy grace we desire to roam in happiness. Thou art our gracious shelter, thou art our great friend. For this, all of us place ourselves under thy protection. Thou art always devoted to virtue, thou art always engaged in the acquisition of virtue. O thou of great wisdom, protect us, therefore, like the wielder of the thunderbolt protecting the celestials.’ Thus addressed, O king, by all the mice, the cat answered them, saying, ‘I do not see the consistency of these two, viz., my ascetic pursuits and this protection (that I am called upon to grant). I cannot avoid, however, doing good to you agreeably to your request. You all, at the same time, should always obey my words. Staying as I am in the observance of a severe vow, I am weakened by my ascetic practices.
