Elayne and I use Quality Cage ferret cages at home, and the Cascade Ferret Network uses Quality Cage ferret cages too (and sells them). These cages are designed for ferrets based upon feedback from ferret owners. We like the heavy gauge 1" X 1" wire mesh they use for cage construction (the floors are 1/2" X 1"), the easy to clean pull out pans, the wide ramps or sturdy tubes used to connect levels, and the layout of the interiors, which minimizes unusable space. The folks at Quality Cage are courteous, and very easy to do business with. Leonard Bottleman [log in to unmask] [Posted in FML issue 2862]
