I ordered a large custom made Northwest cages cage for my 30 year old
Grey in 2004. They did a fantastic job and we got exactly the cage set up she feels the most comfortable in. No sharp edges or places to get caught. Great workmanship. After several years she figured out how to open the spring latch, but we just added a clip in the built in loops. The only thing missing was corner platforms, but I got two from other cage companies. We had them add an opening for nest box-like hideout. It has a flat top, after she got comfortable she uses all parts of the cage, walking on the top, hanging from the ceiling, bathing in a bowl on the floor, playing with a ball on the stand tray below the cage. I wanted to give them a vote because my girl is so happy with her cage now.
