I was messing around with the kits this morning and noticed one of my black kits looks like the fur on the bottoms of his feet are turning white. Does that mean it's not really black as far a genetics and/or showing go? The ears and belly still seem black to me. Other kits in the litter are 4 REW, black with (still) black footpads and a castor. Mom is red and dad is REW.
