Dome tops are a great value. Birds gets the maximum amount of living space. Great if your feathered friend spends a lot of time in his or her cage. Toys hang easily from the top and light readily enters the cage.
Gravity locks on the feeder doors make feeding a snap. Useful if the need arises for guests to feed your pal if you're away. No need to go in through the cage door. The pull out tray and grille are close so your FID won't be eating refuse.
