This article is a study of Delhi's monkey-catchers, municipal contractors who trap and relocate simians. I examine their perspectives, as well as those of planners and residents. Parallel but competing dispositions vis-à-vis monkeys – fascination and repulsion, piousness and annoyance – are detailed. In so doing, the article addresses the following themes: purification and displacement, the neighbour and stranger, multi-species cohabitation, planning and modernization, and the circulation of gift and sin. Three interwoven arguments bear on studies of modernity, urban governance, and post-humanism. First, Indian cities are not becoming irreversibly bourgeois and sanitized; humans engage in varied ways with monkeys and are complicit in their presence, by ritually gifting food. The logic of the gift vies with the desire to cleanse; a supernatural current animates the modernist city. Second, studies of bureaucratic power often presume coherence and efficiency. In contrast, I illustrate official ambivalence to cleansing, as well as structural constraints and makeshift arrangements that conspire against the master plan. Third, I question post-humanist and multi-species theories that seek to transcend Western ontology. The monkey-catchers’ porous taxonomy for human–animal differences affirms human primacy as much as it dissolves dichotomies. [ABSTRACT FROM PUBLISHER]
