Answer: Bestiality is a sin for Jews and Christians according to the Bible (Exod. 22:19,Lev. 20: 15-16, Deut. 27:21). Judaism declares it forbidden to all peoples, including non-Jews (according to the Laws of Noah, also called the Noahide Laws, which are the seven commandments for the Gentiles.) Modern people of other religions also consider bestiality to be a repulsive act, although their codes of religion may not explicitly forbid it.
