While not 'glamorous' in appearance like other breeds, sphinxes are certainly a breed to consider adding if the texture could be done without needing to morph the sculpt to create the sphinx look such as incorporating plenty of wrinkles that are a trademark of the sphinx's appearance. They'd sure be a unique addition! I wanted one of these kitties so badly as a child and my friends (and parents!) thought I was crazy, I actually think they're quite cute in a strange way.
(And a fun tidbit I've gathered while researching cat breeds, sphinxes are considered the most intelligent breed overall by quite a few places including Animal Planet!)
