Booming in Western humanities and social sciences since 1980s“Animal Studies”is evidently multidisplinary and transdisciplinary, which lays a solid foundation for the rising literary animal studies and zoological criticism.Nowadaysliterary animal studies and zoological criticism are promisingly developed,and it is the moment to professionalize the discipline.What is pitiful is that there is still no comparatively independent discourse or theoretical framework.Therefore literary zoocriticism is tentatively proposed as a research perspective and methodology.On the basis of clarifying some crucial terms such as literary zoology,literaryanimal,etc.,this paper aims to illustrate the basic argument, research strategy and core concepts so as to develop literary zoocriticism and relevant critical studies in the 21st century.
