Excellent cage. I purchased a My First home from Petco first...yea it was pretty and had everything but the construction was so cheap my ferret broke a weld when she "Twanged" the cage and she got out..that is all it took she knew how to break them.  This cage is 100% better and heavy duty construction.  Shelves come out so it is easy to clean and access cant get any better.  I just wished I would of bought this cage in the first place instead of tossing $100 out for other cheap cage. Plus later if you want a bigger cage you can add to it instead of buying another cage.
