A tortoiseshell cat is a coat color where the cat is a molted brown cat with black, reddish, or orange patches. They can also have white paws. Tortoiseshell cats have unique genetics. The vast majority of tortoiseshell cats are female, because two X chromosomes are required to produce black, gold and orange coloring.
Just like with a calico cat, the name of a tortoiseshell cat refers to the cats color, not a breed. The color tortoiseshell is a marbelized black and brown (orange/red). Like the young lady in the tree... True tortoiseshell cats have no white markings, and no white in the body color at all.he Calico cat is not a breed but a color pattern that may occur in almost any type of domestic cat.
