Going back to the original question of what is the best two ferrets to keep together, everyone is saying 2 hobs, or a jill and a hob. Whats wrong with 2 jills?? No pregnancies that way. I currently have 2 jills, and have had in the past. Also friends of mine have kept 2 jills, all with no problems atall. Personally i think the jills are better workers, faster round the sets, and tend not to find a warm nest and go to sleep like a hob does. lol.
