After reinforcing the cage with some 12  hardware cloth, this cage worked out perfect for the three rats that I have.  It has plenty of space and I like that you can close off the levels, making it easier for cleaning.  I did end up purchasing the scatter guards for both levels and it helped to where I could have more bedding in the cage without it spilling out.  

The assemble wasnt as bad as I had read in some reviews.  I put it together myself and the only tool I needed (outside of a screwdriver) was a rubber mallet to put some of the parts together.  

Overall Im very happy with this cage and verry happy with the amount of room it has.
