Käfigs

Käfig is a structure designed to confine an animal, person, or object within a bounded space. In German, the common plural is Käfige; the English-form loanword Käfigs is sometimes used in translations. Cages are built from rigid panels or bars and are used in a wide range of settings, from domestic pet enclosures to industrial storage and transport crates.

Construction and features: Materials include steel, stainless steel, aluminum, wood, and durable plastics. Common designs use metal bars or welded wire mesh with door latches, ventilation openings, and removable trays for cleaning. The mesh size is chosen to prevent escape or injury by the target species while allowing airflow. Safety considerations include smooth edges, non-toxic coatings, corrosion resistance, and easy cleaning.

Uses: In homes, cages house birds and small mammals; in agriculture they support livestock management (for example poultry cages, while many systems have moved toward enriched housing). In transport, crates or kennels provide temporary confinement during travel. In laboratories and zoos, cages and enclosures protect animals and staff while enabling observation and care.

Welfare and regulation: Cage design raises welfare concerns, including space, enrichment, and the ability to perform natural behaviors. Many jurisdictions regulate size, enrichment requirements, and allowed materials. Proponents argue cages are efficient and secure; opponents emphasize alternatives such as larger enclosures, aviaries, or outdoor housing. Responsible use emphasizes appropriate sizing, sanitation, and regular inspection.
