Tricia, I've had my Flower for about 2 1/2 years now, and in the time, his coat has gone from dark browns and tans and creams to almost exclusive cream. He looks like a DEW except he's still got some of his original color on his tail and just a smattering of darker hairs along his shoulders. And while the others haven't had so drastic a change, Boobah has gotten lighter and Buttercup has gotten darker in the 3 1/2 years I've had them. So while I'm not an expert, my experience is that a color change is perfectly normal. Wendy and House Penferret: Boobah, Buttercup, Pica, Flower, and Kibble [Posted in FML issue 3302]
