Torbie is a coat pattern rather than a breed. The name blends tortoiseshell and tabby: patches of black-based and orange-based color with tabby stripes, swirls or spots running through them, often with the classic M on the forehead. Brown, blue-and-cream and silver torbies all exist, and one with plenty of white is sometimes called a caliby. Nearly all torbies are female.
Most torbies in shelters are domestic shorthairs or longhairs, so size, coat length and energy vary from cat to cat. Weights run roughly 6 to 14 pounds, and many live 12 to 18 years, so adopting one is a long commitment. Shedding is moderate, and a weekly brushing handles most coats. Folklore credits torbies with a feisty streak, but there's no good evidence that color shapes personality.
