Grapefruit's cage is 32x23 with an interior height of 48 inches and it's a good size for her. If she were in there often, it would need to be much bigger, but we are a mostly cage-free household. She sleeps in there and occasionally is locked in if I am leaving, vacuuming, cooking, etc. It runs $360 (from Kathie).
By contrast Darwin's cage is 34x23 with an inside height of 32 inches. His cage "feels" bigger and has more open space for toys and perches, but this is design more then dimensions. New this cage runs around $500-600 (would never pay that for it though!) Again, too much time inside there and it would need to be bigger, but he can hop around, hang upside down, open his wings, and there is room for 6 or so perches, 3 or 4 toys, and him. He also will be a mostly-out-of-cage bird in time. Otherwise, I'd buy bigger.
That having been said - I'm wondering if you guys think the Kings aluminum 32x25x32 (closer to Darwin's size, of course) is big enough for medium parrots such as small cockatoos, grays, smaller ekkies, larger conures, mini macaws, amazons, etc. If not, what size?
EXCELLENT point about my having said I could get a China produced SS for the price of an American made powder coat - it's the sad ugly truth. Our wallets do talk. It's all the reason for all of us, together and collectively, not to buy those crappy cages to force them to make us something better and instead support our US companies that make better (most expensive) products. But not everyone can afford to do that - and most cages sold are done so by pet stores - especially the large chains. And we all none of them are hoping on the quality control band wagon! i guess it becomes a personal choice about what you believe in or stand for, what you can afford, and what's best for your parrot.
