ANyways that sugar glider cage seems fine, I actually have a friend that has sugar gliders and I think they are one of the coolest pets ever, I have been considering buying a pair for a long time. THey actually are illegal here is CA but you can buy them easily in Vegas. When you buy them as babies you carry them around with you in a little pouch that hangs around you neck, so they are in the pouch on you chest. That lets them learn that you are mommy/daddy, they learn your smell and it keeps them warm. And after a while they can go in their cage, but when ever you let them out they will come to you and sit and play on you. They are the coolest pet ever, and they will fly around your room. They do make crazy sounds though, if they want to sleep and you bug them you will be shocked at the sounds they can make, I can't even describe it, maybe like a big motorcycle starting up, lol very funny. They do require some very good care, you must provide some very good foods for them and always be trying new fruits and veggies, fresh stuff everyday, it is work but they are worth it, but be prepared to spend some $$. I have taken care of my buddies gliders a lot when he goes out of town but I haven't in a while. Oh yeah and you have to have a pair of them, they can't live alone.
And I would go for the flight cages, they are far better than most anything else. Flight cages are wider and longer than tall, which is what keets need, they rarely use height, they will if they have no choice but birds fly horizontally and flight cages give them that room so they can have some room to get around. The cage Animom uses is fine, also the one Rick got is great, I would love that cage, if you have the $$ it is a excellent cage, that one is taller than wide I believe but the width and length is much bigger than most cages so the height doesn't matter.
