This 30 x 18.31 x 18.31 inch flight cage gives birds like parakeets, cockatiels, lovebirds, finches, budgies, and canaries plenty of room to move with 0.4-inch grid spacing throughout. A removable divider shelf lets you split the single cage into two independent living spaces, which is handy when housing different species that shouldn't share a space, or simply combine them back into one open cage when you have a single bird. The secure door design keeps birds safely inside while making daily access easy, and two feeding doors let you separate food types for different birds. Multiple perching poles are built in for resting, and a bottom sliding tray pulls out for fast cleaning while the grid floor keeps droppings from piling up. Made from high-quality carbon steel weighing 5.56 kilograms, the frame is sturdy enough for daily use, and the cage is designed to stack with additional units if you need to house more birds.
