A little bird told us that fitness was a big deal so we ve been looking into the Prevue Pet Products Divided Flight Cage - Black. This roomy divided cage helps encourage exercise for Finches or other small birds by dividing the space so they have to get down and stretch their legs every now and again. Each side is outfitted with an opening door feeder cup and a pair of perches. A removable tray at the bottom makes cleaning easy and the design is even stackable to allow for more cages.
