Honestly, I don't see a were-ferret as anything odd.

But then, I have spent a lot of time with Due South. Magical realism and the quirky humor means when you get to a fic with Fraser as a were-otter, it's "Yeah, I can see that." and then later Stargate Atlantis (crack!fic ahoy, what haven't those boys been turned into by now?) well, I'd be surprised if a kink meme didn't surprise me from time to time.
