The term "wire cage" is a common expression used to describe an enclosure made from wire mesh, often used for confining or restraining animals. The wires are typically arranged in a pattern that creates a strong yet flexible structure, allowing air and light to pass through while still providing containment. These types of structures can be found in various settings such as farms, zoos, and research facilities where they serve different purposes like housing for livestock or enclosures for wild animals. The phrase "wire cages" is often used interchangeably with other terms such as "cage", "pen", or "enclosure".
