"God's teaches us to refrain from inflicting unnecessary pain on any animal. And not only physical pain; an animal can suffer mental pain too. … It is an important part of Torah education to train children to respect animals as sensitive beings which should not be unnecessarily deprived of the joys of life. … It seems doubtful from all that has been said whether the Torah would sanction "factory farming," which treats animals as machines, with apparent insensitivity to their natural needs and instincts."
