I got this cage for my Goffin Cockatoo and was a little disappointed in the thickness of the wire, which is why I gave it four stars instead of five. But my bird is quite the escape artist and he has not gotten out of this one yet (as long as I keep padlocks on the feed doors!) and he really seems to enjoy the layout of the cage.  It looks very nice in the house without being too obtrusive and the casters roll very easily on the hardwood when I have to move it for cleaning.  Very happy with this bird cage!
