"Laws protecting, impacting, regulating and controlling animals have been an integral part of American jurisprudence since the very early days of colonization. However, the distinct field now known as "Animal Law" is a relatively new development. Animal Law brings together statutes and cases form multiple fields of law that consider ... the interests of animals or the interests of humans with respect to animals."
