This wrought iron flight cage is sized for 3 to 4 medium or large birds, such as African grey parrots, monk parakeets, conures, and lovebirds, with a 36.6 x 22.8 x 39 inch interior and 0.6 inch bar spacing that gives them room to jump and stretch. The flat-top design and three built-in perches match birds' natural habits, and side wires let them climb and play. A powder-coated finish resists rust and water, and thickened tubes plus a reinforced frame keep the 59.5 inch tall cage from warping, with a secure latch that stops birds from pushing the door open. Plastic feeders cut down on beak wear, and a shelf underneath holds extra food and supplies. Four 360-degree swivel casters make it easy to roll the 39.24 pound cage from the living room to the balcony for fresh air. At cleaning time, the bottom tray slides out for quick emptying, and a metal grate keeps birds off their droppings.
