We bought a large suet holder to use as a second hay rack. Can't beat the price! It loads from the top and the side pieces you see are for the birds to perch on. We used them to mount the suet holder with.
Good use for a bird feeder!
I have one as well in my cage too. I have it hanging on the lower level so if the piggies feel lazy they don't have to go to the loft to get hay.
