Mutation Fox Tail

I interviewed a nice woman yesterday at the local flea market. She and her husband have been selling furs, leather, bones, crafts, native american goods, etc. for 15 years. After the interview, I commented on how I knew most tails that were there, except this one. She said it was a mutation, and then said "It's yours." After me stupidly saying "Really? Seriously? Mine" for several seconds, it sunk in that she really was giving me a beautiful fox tail for free.

Now, what in the world kind of mutation is this? It's an off-white cream color with darker spirals since the tail is twisted. Maybe an arctic mutation of some sort, right? At 16.5 inches long, it's nice.

To see a beautiful picture of it, I put one in my scraps. It's just a showy picture. [link]
