Open top design: To keep your bird stimulated, the roof of our hanging birdcage can be opened and locked up at will. It includes a perch that keeps the top doors open for the birds to stand on and can be closed to give them a safe enclosed home. Free accessories: This fancy bird cage comes with four polished wooden perches and a swing for your birds to rest and four feeding bowls for your convenience. Detachable rolling stand: This rolling bird cage sits on four 360-degree swivel ball-shaped wheels, making it effortless to move around. The upper cage can be used separately thanks to the detachable design. You can place/carry the cage without the stand at will. Specifications: Color: black; Material: steel, plastic; Overall dimension (with top opened): 18” L x 14” W x 64’’ H; Bar spacing: 0.4’’ Solid construction: Crafted from quality metal wires covered with oxidation-resistant paint, our bird cage is a strong metal structure with an easy-to-clean plastic base, and the sanded wooden perches are safe for the bird’s claws.
