I have two 4 (well now almost 6 weeks old) baby girls in my DCN, and it's perfect! I blocked off the bottom part of the cage, so they can't have the whole cage yet. They are perfect in it, and can only stick snoots out of the bars, just barely. If it was the ferret nation, it would be different.
Thank you! I had the cage set up and ready and they seemed ok but I was a little nervous going into night time when I can't monitor them to make sure they don't disappear on me. Haha, again thanks so much!
Yes I put my babies in there when they were about 3 weeks old. It wasn't the bar spacing I was worried about, but the height (falling). I blocked it off so they only had half the double cage, and I put in lots of rope nets, hammocks, ledges, etc. so that if they fell it wouldn't be far before they caught themselves on something.
