Hi FML family: I am asking for advice from any Ferret Nation Cage owners. I currently have 9 ferrets who bunk in groups of three. While my experience with Ferret Nation cages is limited, I really like many of their features. I did read about concerns discussed on the FML recently and checked out the custom made ramp and shelf covers. I am torn between buying a single level unit with a double unit or buying a double unit with an add on. I have space enough for either set up. These are my questions: 1. How much of an inconvenience is the height of almost 7 feet (for the 3 units) for reaching the top cage? 2. Does the additional weight from a third level affect the castors or leg stability over time? 3. How stable is this height, do they tip over and does having rambunctious ferrets in the top level effect stability? 4. Has anyone devised a way to hang hammies on the left side of the cage evenly since the door can't be used to hook onto if it is your primary use door? 5. Got any other points that I may want to be aware of? Thanks for your expertise and opinions.
