Oh yay, I saw your cage in the Photo Gallery and it looks GREAT, I think it's exactly to mine. Is it 30x18x36?
Your little ones are definately too spoiled hihi...And about the cleaning, I had the same problem at first too. The bottom tray just wont slide out as easily. So what i've been doing is I just don't use the tray at all. Instead, I lay newspaper on the bottom (inside) of the cage and change it 2x (or once) a day. Not only it's faster but cleaner at the same time too. I don't like the fact that their poops get stuck on the bottom wires, I'm kinda a clean freak when it comes to their poops get on anything like toys, wire, perch, etc.
