This article reflects upon the experience of conducting research into a UK-based, though internationally-renowned, animal rights group. The article firstly rationalizes the ethnographic research methodology used to approach Stop Huntingdon Animal Cruelty (SHAC). Secondly, it describes the effect of unforeseen factors (from adverse media attention to ongoing criminal investigations) on the Author's ability to forge research relationships with informants within the movement, and how these challenges were overcome. Given the interdisciplinary focus of the project, this manuscript will be of interest to scholars wishing to investigate ‘hard-to-reach’ social groups, and particularly those who have written on reflexivity and power in research relationships.
