cage

A cage is an enclosure often made of mesh, bars, or wires, used to confine, contain or protect something or someone. A cage can serve many purposes, including keeping an animal or person in captivity, capturing an animal or person, and displaying an animal at a zoo.

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.

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

A mesh is a barrier made of connected strands of metal, fiber, or other flexible or ductile materials. A mesh is similar to a web or a net in that it has many attached or woven strands.

In computing and mathematics, "mesh" may refer to:

• A description of an object by a collection of small simple shapes, commonly used in numerical simulations and computer graphics
• Types of mesh in computational mathematics
• Polygon mesh, a partition into polygons
• Mesh (mathematics), a partition of an interval
• Mesh generation or "grid generation" or "meshing," algorithms and software for creating meshes
• Mesh network, a highly interconnected network of computers or networking hardware
• Bluetooth mesh, networking standard by Bluetooth SIG
