Recently, animal studies has started to gain popularity. This interdisciplinary field investigates the human-animal relationship from different perspectives, including philosophy, cultural studies, and biology. In 2008, at least three books explored themes related to animal studies: Matthew Calarco, Zoographies: The Question of the Animal; Jodey Castricano (Ed.), Animal Subjects: An Ethics Reader in a Posthuman World; and Cora Diamond, Cary Wolfe, et al. (Eds.) Philosophy and Animal Life. Each volume approaches animal studies from a different viewpoint (Continental philosophy, interdisciplinary, and Wittgensteinian), but they also share many themes. This review paper discusses the differences and similarities between the volumes and highlights the directions in which animal studies is developing. It is argued that an emphasis on "direct" perception or experience of animality and heterogeneity, and an exploration of otherness, are elements that all these books share, and that are relevant to animal studies.
