encagement

Encagement is a term used in zoological and ethical contexts to denote the act of placing an animal or object into a cage or enclosure, or the state of that confinement. In English usage it is relatively uncommon; more often the idea is expressed with terms such as enclosure, confinement, or captivity. The word derives from en- (to make or cause) and cage, reflecting its literal sense of placing within a cage.

In practice, encagement appears in zoological, veterinary, and museum literature to describe housing of animals or specimens. In zoos, encagement refers to enclosures designed to confine animals while providing appropriate space, shelter, and enrichment. In laboratories and shelters, it can describe temporary or long-term housing. In museums or aquariums, preserved specimens may be kept in cages or containers for display or study.

Ethical and welfare considerations are central to discussions of encagement. Debates focus on balancing safety and welfare, the need for enrichment, space, social grouping, and the purpose of confinement. Critics argue that prolonged or inappropriate encagement can cause stress, while proponents may point to safety, conservation, veterinary care, or educational value. Proponents and critics alike emphasize the importance of design features such as larger, more naturalistic enclosures, environmental enrichment, and opportunities for species-typical behavior.
