Cages are structures made of bars or wire that are used to confine animals or objects. They can be found in zoos, where they keep wild animals like lions and monkeys safe while allowing visitors to see them. Cages can also be used for pets, such as birds or hamsters, providing them a secure space to live and play. In addition to animals, cages can serve other purposes. For example, storage cages are used in warehouses to hold items securely. Some people even use cages for art projects, creating unique displays. Overall, cages help keep things organized and safe.
