African Grey parrots require a large cage that allows them ample room to move, stretch, and play. The cage should be sturdy and safe, with appropriate bar spacing to prevent injuries. It should be placed in a social area of your home to allow interaction but away from kitchen fumes and excessive noise, which can cause stress. Additionally, provide a variety of perches of different thicknesses and materials to support foot health, along with toys and puzzles to keep the bird engaged and mentally stimulated.
