The cage is large enough for a Macaw and the slide out bottom tray and cage floor make for easy cleaning.  The assembly instructions are pretty lacking in detal but two people can figure out the assembly fairly quickly.  We do use padlocks on the main door, food doors and the floor screen but this is due to prevent any determined Hawaiian Mongoose from gaining entry to the bird cage while the Macaw is in it or any people for that matter.  Replacing the factory perch with tree limbs is pretty normal for any new Macaw cage.  All-in-all the Silverado Macaw cage is a winner for Macaw use.
