Those boxes sound great. There is only one caution I'd like to add. A friend of mine made 3 beautiful wooden sleeping cabins for me with lids that could open for cleaning and a round hole in the front for the ferrets to go in and out. Perfect, one would think. The trouble was that a few ferrets would get in each cabin, one ferret would get too hot and lie half in and half out of the hole. The next ferret that needed to leave would get stuck trying to get past the ferret in the hole. One was stuck at his neck while trying to get out, so I had to go to plan B. Currently, I have removed the lids of the cabins and just rest them sideways on the top. It does make the cabins safe but defeats the purpose of giving the ferrets a dark place. Even enlarging the hole would just mean that more ferrets could lie half in and half out of the cabin. What I hope to do in the future is to enlarge the hole or remove the entire front of each cabin and make make an expandable entry with material and elastic. I haven't figured out exactly how yet, but it may come to me if I dwell on it for long enough. I guess with your boxes being made of cardboard, or if you don't have multiple ferrets, this problem may not occur, but it's just a thought. Cheers, Shirley [Posted in FML 5412]
