I have to say this is the by far the best cage that I have ever owned.  I bought this for my chinchilla and he absolutely loves it.  I do highly suggest going to your local hardware store and purchasing plexiglass pieces to fit the doors on the bottom or the shavings will be EVERYWHERE.  I just brought the cage pieces to the store prior to assembling and had them cut them to fit while I was there.  This is a great fix and has cut back on clean up drastically.  I love how the doors open all of the way.  This makes very easy access to the entire cage which also aids in cleanup.  Assembly would have been much easier with 2 people but I did fine on my own, it just took extra time.
