Mbh 12.165.1g

He should then make a present of a thousand kine with one bull (unto a good Brahmana). Doing all this, he would regain his purity. Having slain a Vaisya one should perform such a sacrifice for two years and make a present of a hundred kine with one bull. Having slain a Sudra, one should perform such a sacrifice for one year and make a present of a hundred kine with one bull. Having slain a dog or bear or camel, one should perform the same penance that is laid down for the slaughter of a Sudra. For slaying a cat, a chasa, a frog, a crow, a reptile, or a rat, it has been said, one incurs the sin of animal slaughter, O king! I shall now tell thee of other kinds of expiations in their order. For all minor sins one should repent or practise some vow for one year. For congress with the wife of a Brahmana conversant with the Vedas, one should for three years practise the vow of Brahmacharya, taking a little food at the fourth part of the day. For congress with any other woman (who is not one's wife), one should practise similar penance for two years. For taking delight in a woman's company by sitting with her on the same spot or on the same seat, one should live only on water for three days. By doing this he may cleanse himself of his sin. The same is laid down for one who befouls a blazing fire (by throwing impure things on it). He who without adequate cause, casts off his sire or mother or preceptor, surely becomes fallen, O thou of Kuru's race, as the conclusion is of the scriptures. Only food and clothes should be given, as the injunction is, unto a wife guilty of adultery or one confined in a prison. Indeed, the vows that are laid down for a male person guilty of adultery should be caused to be observed by also a woman who is guilty of the same.
