I was told that the electroplated steel cages are bad. The ferrets can chew off the paint. I can see where that could happen. Does anyone have a comment on this? Also my son and I are looking for a new cage maybe a "castle" for our babies. We haven't seen anything better than a ferret playpen by midwest. It didn't look safe to me just big. The levels are narrow and the ramps are steep. Are there any suggestions on this: I think we may build one. [Posted in FML issue 1781]
