A cage is a structure made of bars or wire that is used to confine animals or objects. It provides a safe environment for pets, birds, or other creatures, allowing them to be contained while still being visible. Cages can vary in size and design, depending on the type of animal they are meant to hold, such as birds, rabbits, or reptiles. Cages are commonly used in zoos, pet stores, and homes. They serve various purposes, including housing pets, protecting wildlife, and facilitating research. Proper care and maintenance of a cage are essential to ensure the well-being of the animals inside, as well as to prevent any potential escape.
