I once was looking to get a cat and found the goofiest looking idiot on Craigslist. Turns out, it was a purebred Exotic Shorthair that was surrendered to a shelter because it didn't look fucked-up enough (it could still kind of breathe through its nose). New owners wanted to recoup costs because they adopted another cat that was "more playful" and the exotic was getting eye-goop on their white carpets. A wonderful standard for purebreeds!

I changed him name from "Luigi" to "Waluigi", and he was best best buddy for many many years.
