My 5 month old female ferret has blue/black skin on her entire torso area. Not on her head or neck. She eats ferret food and is acting healthy. Is it just a common aging thing? Or is something serious wrong? My two other ferrets have pinkish healthy looking skin. If you can offer any advice please email me because I have been unable to receive the entire FML file (Just the first few questions/answers). Thank you. AntsLove [Posted in FML issue 1321]
