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.
Color does not affect the lifespan of a cat, so a tortoiseshell cat can expect to live 13 to 17 years or longer. Paying close attention to health, including regular vaccinations and checkups with a veterinarian, can help ensure a long lifespan for a tortoiseshell cat. Learn more about Cats
