Gilles Deleuze and Félix Guattari use as a key example of becomings becoming-animal. Becoming-animal involves both a repudiation of the individual for the multiple and the human as the zenith of evolution for a traversal or involution across the speciesist plane of consistency. Deleuze and Guattari delineate the Oedipal animal, the pack animal and the demonic hybridisation of animal, human and imperceptible becomings. Various commentators have critiqued and celebrated Deleuze and Guattari's call to becoming-woman. In his taxonomy of living things Aristotle places women at the intersection of animal and human, so becoming-animal as interstices raises urgent feminist issues as well as addressing animal rights and alterity through becoming-animal. This chapter will invoke questions such as ‘how do we negotiate becominganimal beyond metaphor?’, ‘what risks and which ethics are foregrounded that make becoming-animal an important political project?’ and, most importantly, because becoming-animal is a queer trajectory of desire, ‘how does the humanimal desire?’
