Snugasabug, here's a photo of an adult black smoke Maine Coon cat. Since your girl is going to have medium long hair, hey, maybe she's a Maine Coon cat! They are quite a large breed of cat. You don't often see the black smoke colour in DSHs (Domestic Shorthairs) as it's quite a rare colour variation, related to the silver tabby gene.
