Sorry, didn't receive notification of a reply. I have a 9 year old single male that I have in it right now. I don't like it. I don't have room to put anything, so I'm planning on getting him something better with my tax money.
Shoot for a ferret nation or critter nation if you want a large cage. These will allow for proper shelving and an exercise wheel if you choose to purchase one.
Quality cage (quick google search will bring up their site) is also a great place to order chinchilla cages and wheels from. They offer packages with correct shelving included. (Or you can make them at home)
