Tortoiseshell is a coat pattern rather than a breed. A tortie's fur blends black-based and orange-based colors in patches or a fine mottled mix, usually with little or no white. Nearly all are female, and most are domestic shorthairs or longhairs, though the pattern also appears in breeds like Maine Coons and British Shorthairs. Typical weight runs 6 to 14 pounds, and many live 12 to 18 years.
Torties have a reputation for "tortitude," a bold, opinionated streak. The evidence is limited and mostly owner impressions, so expect anything from shy to pushy. Shedding is moderate, and a weekly brushing keeps hair off the furniture. In a Kennesaw home, a cat's age, history and socialization will tell you far more about daily life together than her color does.
