I hand made my first chinchilla cage.  It was five by five feet, and my chins loved it!  There were several problems though: I couldn't clean it, couldn't get it out of my apartment (too big to fit through the door), and it rattled like crazy when the furries would jump around. 
 
The feisty ferret home fixed all these problems.  It is tall and elegant, very easy to fix, and all of the levels are great for my girls to jump around.  I highly recommend this for the price.  Great value!  

Also, I didn't think my chins would use the hammock, but they LOVE it!

It was difficult to assemble.  I accidentally put many of the parts upside down.  The directions are not the clearest, but I eventually figured it out.
