Black. Always. A little white tache, bib and toes is very appealing, but overall, the best cats are little and black.
Strangely, I've always been inflicted with had various Tabby shades and one longhaired Tortoiseshell and white. --Because I'm a sucker for a hard luck story when it's packaged with cute little toes, whiskers and pointy ears.
But that means a lost little black kitten will always find a home here when it finds it way to me.
