In this intervention piece, I attempt to understand the role of anger and silence in creating beyond-human multispecies worlds always involving or ending in failures. Drawing on vignettes from archival, autoethnographic and interview research, this paper explores how silence and anger are entangled political forces implicated within failures of caring for animals in worlds that do not. Exploring the disrupted worlds of vegans; human-chicken relationships; and histories of anger within animal activism, the coalescing of silenced angers and angry silences in beyond-human research are considered here as part of flourishing failures necessary to transforming worlds. By attending to the role of failure as necessary within beyond-human research process, I explore the implications of silence and anger as a failure of mutual flourishing, where more often the focus is on successful becoming-togethers.
