Construction
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 too closely together for the intended captive to slip between them, or with windows covered by a mesh of some sort.

in which the captors "pulled him into a cage and brought him to the king of Babylon".
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.
Animal protection associations have often argued for improving transport conditions in cages and for bans on battery cages, especially for egg-laying hens. The European legislation is constantly changing, but consumer behavior also influences breeding conditions.
Trapping
Cages also serve as a trapping tool. This is a common and illegal purpose of the cage, as poaching is illegal itself. These type of cages are used to trap an animal, or hold them for a certain period of time. U.S. President
