Someone who has had parrots designed this cage.  It has features I never considered before I bought it.  The feed doors are so readily available and the slide out bottom rack makes for easy clean up.  The seed catcher eliminates most of the seed throwing messes I have had in the past and my parrot just loves to perch up in the domed area. I I bought him a long braided rope perch for there.)  Terrific product.
