The aviantelligence is a good cage. It is only 18 inches deep though. The latches on it are like these:
I switched them out and put on Window Sash Locks:
I feel safer with these and was afraid my GliderKids would be able to flip the original style locks open if they were not slid over to fully lock.
The pan that comes with the Aviantelligence cage is also too small for the space under the cage. I replaced the pan with a deeper one from Martin's Cages. Their 18 x 30 x 2.5 deep pan fits perfectly and is snug against the bottom grate of the cage.
I have 4 gliders in it and they have plenty of room.
