Alicia- My silver mitt male Jasper has a lovely white underside and chest, but I've noticed that at times it yellows slightly. And I have no idea why. It's usually in the shoulder blades, just as you said. I hope this doesn't sound bad, but it has only been a matter of curiosity to me, and not much of a concern. His energy level is great, he's eating fine (my jiggly little fat boy!), his stools are normal and he's in perfect health. The skin underneath the yellow fur looks fine and he's not sore. I guess what I want to say is, if there's no other signs, then Fidgit is probably just fine. If someone else has a similar experience, or if I'm totally missing something, now's the time to speak up.
