Categorizing non-human animals (henceforth "animals") as human commodities implies reducing their lives to mere market values. However, precisely because some of these animals' lives and experiences are complex, such commodification often leads to a form of resistance from the animals commodified. Therefore, examining the many ways in which animals are commodified also requires one to focus on the many ways in which animals resist their own commodification. At the same time, since resistance tends to require a response from the resisted, looking at resistance also implies exploring the ways in which the resisted react to those who resist commodification. It thus appears necessary to explore commodification and resistance alongside the impact that this resistance can have on the resisted/commodifier and how, in some cases, this response has agency in triggering a significant transformation.However, defining animal resistance in the context of their commodification is far from straightforward. We see this Special Issue as a way to provide potential avenues for exploring both resistance and commodification and the ways in which they intertwine.First, we agree with Kohn that resistance and agency are not the same thing, yet that both notions are useful and interconnected (2013). Nonhuman agency, roughly conceived as the ability to act independently and, by doing so, to make some sort of difference to other entities/actors, takes many forms and exists within as well as beyond human structures (Kohn 2013, 91). However, it is not the topic explored here. Rather, our focus is on animal resistance in the context of their commodification, a relation which necessarily emerges within a human structure. Nonetheless, the specific forms of animal resistance that emerge from their
