I recently acquired a Goffin Cockatoo.  The cage he was in was ok but he looked cramped.  I was going to get a stand so when he was out of the cage he could be free.  When I saw this design I immediately fell in love with it.  It has plenty of room for him to climb and when I slide the door open in the rear he can climb on the perch which is the stand.  At night he likes to stand on the perch that is under the perch tray.  I guess for more secure feeling.  I'm really happy that he is happy!

Pros: Sturdy, easy to roll around, wide seed catcher, ample space
