Acage is an enclosure often made ofmesh, bars, orwires, used to confine, contain or protect something or someone. A cage can serve many purposes, including keeping an animal or person incaptivity, capturing an animal or person, and displaying an animal at azoo.[1]

Construction

[edit]

Since a cage is usually intended to hold living beings, at least some part of its structure must be such as to allow for the entry of light and air. Thus some cages may be made with bars spaced closely together for the intended captive to slip between them, or with windows covered by a mesh of some sort.

Cages often used to confine animals, and some are specially designed to fit a certain species of animal. One or morebirds,rodents,reptiles, and even larger animals of certain breeds are sometimes confined in a cage aspets.

Animal cages have been a part of human culture since ancient times. For example, anAncient Greekvase dated to 490 B.C. depicts a boy holding a possibly domesticated rabbit on his lap, with a cage with an open door in the background.[2] The biblicalBook of Jeremiah refers to a tribe being like "cages full of birds",[3] and theBook of Ezekiel describes the capture of alion in which the captors "pulled him into a cage and brought him to the king of Babylon".[4]

The different laws governing the keeping of animals in captivity generally provide for the size of cages or minimum equipment, depending on the species, whether for transport or for breeding. Swiss legislation, for example, defines minimum absolute internal dimensions for pet cages, but the Swiss Animal Protection organization (PSA) states that even if these dimensions comply with the law, they are far from being in line with the needs of species. It is therefore necessary in practice to provide a much higher vital space to ensure the well-being of the occupants.[5]

Animal protection associations have often argued for improving transport conditions in cages and for bans onbattery cages, especially for egg-laying hens. The European legislation is constantly changing, but consumer behavior also influences breeding conditions.[6]

Trapping

[edit]
Main article:Trapping

Cages also serve as a trapping tool.[7] This is a common and illegal purpose of the cage, as poaching is illegal itself. These types of cages are used to trap an animal, or hold them for a certain period of time. U.S. PresidentTheodore Roosevelt used a cage himself to capture abear, as the cage serves a purpose for capturing large animals.

In history, prisoners were sometimes kept in a cage. During theVietnam War they were referred to as "tiger cages".[8] Captives would sometimes be chained up inside into uncomfortable positions to intensify suffering. In medieval England, King Edward punishedRobert the Bruce by having two of his female supporters encaged in public.

Entertainment

[edit]

Cages are used in various forms of entertainment to create excitement from the sense that the entertainers are trapped in the cage. For example,cage dancing "refers to a scantily-clad feminine dancer, perhaps wearing a mini-skirt or hot- pants, and (supposedly) trapped inside of a hanging bird cage".[9]Cage fighting involves two combatants, usually engaging inmixed martial arts, inside a cage-like structure, and "conjures up the image of two combatants trapped in a cage, trading vicious blows as the audience bays for blood".[10] InAustralia, a ban on the use of "cage-like enclosures" at such events was lifted in 2014.[10] Steel cages are also one of the oldest form of enclosures used inprofessional wrestling. The first "steel cage match" of any kind took place on June 25, 1937 inAtlanta, Georgia.[11] This match took place in a ring surrounded bychicken wire, in order to keep the athletes inside, and prevent any potential interference.[12]
