Today’s daf touches on the subject of cruelty to animals. One of the most famous teshuvot written on this subject was by Rabbi Yechezkel Landau – the author of the Noda B’Yehuda. In a responsum on the subject of the permissibility of hunting in Jewish law the Noda B’Yehuda deals with two main questions:
1. Tza’ar Ba’alei Chaim (cruelty to animals); and
2. Ba’al Tashchit (being wasteful).
I found a nice summary of some of his ideas on the Ohr Sameach website which I quote below. This answer by Rabbi Mendel Weinbach deals with two other issues which is interesting in itself.
“Question: Some friends have invited me to join them on a safari to Africawhich will include hunting wild animals. Is hunting proper for a nice Jewish boy?
Answer: This question was put to the rabbi of Prague, Rabbi Yechezkel Landau, over two centuries ago. His answer, as it appears in Responsa Noda B’Yehuda, rejects the idea of hunting on cultural, ethical and halachic grounds.
“Who are the hunters mentioned in the Torah?”, he asks rhetorically. Nimrod and Esav, the two individuals identified as hunters, were also the personification of rebellion against Heaven and cruelty towards man. Hardly models for a nice Jewish boy!
He also calls attention to the Jewish custom of wishing someone who wears a new article of clothing that he live to see it wear out and be replaced by another (“tibaleh vetitchadesh“). This blessing is withheld, however, in regard to items made of leather, such as shoes, because it implies the death of an animal to make such renewal possible. If such compassion for animals is expected of us in the blessing we offer, he concludes, how much more so in regard to refraining from slaying them simply for the sake of pleasure.
After stating these reasons based on mussar (ethics) the author issues his ruling that hunting is forbidden because of the risk it presents to the hunter. (“Just as the hunter is out to kill his prey, the animal is out to kill the hunter.”) If someone hunts for his livelihood he is permitted to expose himself to this level of risk just as the Torah permitted one to climb high fruit trees, cross oceans and travel deserts for his livelihood despite the fact that each of these carries with it a degree of risk. But if hunting is done simply as a form of sport one is guilty of exposing himself unnecessarily to such a degree of risk, and therefore violates the Torah command to guard against danger to life, a sin that makes his situation even more precarious.
