A lot of cat colors and characteristics started off as carefully-husbanded mutations. You may want to post Basil's pictures on a vet school website and see what kind of opinions you get.
Thanks for checking! I'm very curious what he's going to turn out like...or if he's done turning colors.

Good idea...I'll check out UC Davis' site....thanks!
