Even with so many smokes on my pedigrees I still have solid color kittens occasionally. My Life of Palmetto and GC Purrlamb Eclectic of Klasik. All of their offspring that I kept always went back to one of my smoke males, however. Some have a little of this color on their muzzles. You then spend the next six to twelve weeks waiting for the undercoat to start coming in.
Smoke kittens go though some very dramatic color changes.
Some kittens, because of a very dense undercoat, will have a silver body with only a black spine line for several months. If you just sit back and wait some more, gradually you will see the black top coat come in and cover first the shoulders and gradually the body, almost like a mantle. I personally do not find this to be true, and have never felt penalized for this in the show ring. In all my years of breeding smokes I have never found a judge that would not put a good smoke up in the finals. It might not be my smoke, but judges do final good smokes.
