They are pre-drilled for cages. I used two that I ordered for a recycled hanger for my daughters' two parrots. I removed the two protruding studs from the rod branches and swapped them out to fit the pre-drilled holes in the top of the hanger. I gave it to her about a week ago and got positive feedback on how much parrots like it. Another good project from the grandfather of parrots. picture below.
