How do you describe a cage?

A cage is a structure designed to confine or enclose animals, typically made of bars or wire mesh that allows visibility and ventilation while restricting movement. It can vary in size and shape, often serving as a habitat for pets, wildlife, or laboratory animals. Cages can be perceived as protective enclosures or as restrictive barriers, depending on the context in which they are used. Ultimately, they symbolize a juxtaposition of safety and confinement.
