This book offers the first systematic theological exploration of animal pneumatology, examining the role of the Holy Spirit in relation to non-human creatures. While animal theology has been significantly advanced by theologians such as Andrew Linzey and David Clough, no dedicated monograph has yet brought pneumatology into sustained conversation with animal existence. This book addresses that lacuna by developing a comprehensive theological framework that integrates biblical, historical, and contemporary sources.   Each chapter explores a distinct dimension of pneumatology?creation, predation, redemption, eschatology, and creaturely communication?in relation to non-human animal life, arguing that the Spirit?s presence and activity extend beyond humanity to encompass all sentient creation. By foregrounding the Spirit?s relational, sustaining, and communicative work, the book challenges anthropocentric assumptions that continue to shape both theology and ethics.
