Critical animal studies (CAS) is an interdisciplinary field in the humanities and social sciences and a theory-to-activism global community. It emerged in 2001 with the founding of the Centre for Animal Liberation Affairs by Anthony J. Nocella and Steven Best, which in 2007 became the Institute for Critical Animal Studies (ICAS). The core interest of CAS is ethical reflection on relations between humans and other animals, firmly grounded in trans-species intersectionality, environmental justice, and social justice politics. Scholars in the field seek to integrate academic research with political engagement and activism.
