In this book, we reclaim the term "resistance" by exploring how animals can "resist" their commodification through blocking and allowing human intervention in their lives. In the cases explored in this volume, animals lead humans to rethink their relationship to animals by either blocking and/or allowing human commodification. In some cases, this results in greater control exercised on the animals, while in others, animals' resistance also poses a series of complex moral questions to human commodifiers, sometimes to the point of transforming humans into active members of resistance movements on behalf of animals.
