Why can't you show silver foxes in dove, champagne or silver? Is it purely because they wouldn't be as contrasting? Can you even make PE foxes, or does the chinchilla gene affect the top colour of the pale varieties? Not that I could see that it would, unless there's some kind of loci linkage issue, but I would have thought that the tan gene would confine the chinchilla effect to the belly like any other fox variety. I think dove mice with white bellies would be extremely attractive. But then I think anything dove based is extremely attractive LOL.
