Maybe you should look into trying to develop Smokey's peculiar mutation into the bases of an exotic breed.  I'm not familiar with cat breeds (the only cats I ever owned were found in an alley), but I distinctly remember a National Geographic article on cats from a few years ago, that mentioned one exotic breed that was called the 'Sphinx', because it was hairless.  It had been bred especially for cat lovers who are unfortunately allergic to cat hairs.  I'd say that an extra-toed cat would be either extra feisty around dogs, or extremely adept at climbing tress (even more so than most cats) or both.  I'm sure that there are other possibilities that could come to mind, but I can think of any right off the cuff.
