Jim Makowski- I don't think you have anything to worry about.....at our last club meeting, Dr Judi Bell gave a presentation and brought up that very topic - it is not unusual for fur to have a bluish cast to it as it grows back in from any significant hair loss - shaving from surgery, coat changes, etc. She may have been stressed enough to lose enough fur for that to happen. I have several kennel cab carriers set up around the house for my ferrets to play in. They have litter pans, etc in them....it is much less stressful for them when I've taken them on vacation with me (in the old days when I only had 2!) to travel in something they are familiar with and used to. You might want to try something like that the next time you go away and see if it makes a difference. BTW, she did give an explanation for the blue fur, but I can't remember what it was.
