A bird cage is a structure designed to house pet birds, providing them with a safe and comfortable environment. Typically made of metal or plastic, these cages come in various sizes and shapes to accommodate different species of birds, such as parakeets, canaries, or cockatiels. They often include perches, food and water dishes, and sometimes toys to keep the birds entertained. Bird cages are essential for pet bird care, as they protect birds from predators and hazards in the home. Proper ventilation and space are important features, allowing birds to move freely and stay healthy. Regular cleaning and maintenance are necessary to ensure a hygienic living space for the birds.
