The Hagen cockatiel cage is the only cage I have seen with wider spacing and heavier gauge wire, very appropriate for medium sized birds. The Hagen parrot cage is exactly the same dimensions, but with a heavier gauge wire, a larger door, and different placement of cups. The parrot cage plastic tray is interchangeable with the cockatiel cage tray. The cups are interchangeable, and I have a whole bunch of extras. They also come with floor stands which can fit inside the cage for storage, which allows the whole kit to be sold in a single box. Since the cage is one solidly welded piece, there are no bolts to tighten, no parts to come loose, no seams to collect gunk, and a significant weight could fall on it without crushing it.
The best news is that the custom fit cover I sewed for Charlie, who no longer gets covered at night, fits perfectly on Louie's cage. He likes to be covered, but Charlie prefers to sleep in the birdie tent I made for her. I have never seen cages this well designed, in this price range, and I wonder if anyone else appreciates them as much as I do. They last for years and years without cracking or rusting.
