Book excerpt: This book provides an in-depth investigation into the practices of animal housing systems with international contributions from across the humanities and social sciences. By attending to a range of different sites such as the zoo, the laboratory, the farm and the animal shelter, to name a few, the book explores material technologies from the perspective that these are integrated parts of a larger biopolitical infrastructure and questions how animal housing systems, and the physical infrastructures that surround central human-animal practices, come into being.
