The Bird Life Ladder for Small Birds provides health and entertainment benefits to keep your feathered friend flap happy. Each rung of the ladder is coated with a lightweight cement that’s made from crushed seashells. Those shells add calcium to your bird’s diet for health perks. The rough texture also trims your birdie’s nails and beak， so say bye-bye to those sharp edges. The ladder includes metal hooks that let you easily attach it to any wire cage.
