The American Shorthair descends from working cats that traveled on settlers' ships to keep rodents off the cargo, then guarded barns and homesteads across North America. In the early twentieth century the sturdiest of them became a pedigreed breed, first called the Domestic Shorthair and renamed in the 1960s. Today it's a solid, muscular, medium-to-large cat with a broad face, full cheeks and a thick, hard-textured coat in dozens of colors, with the silver tabby the classic look.
Shedding is moderate, and the dense coat sheds most in spring, so a weekly brush at home is usually enough. Appetite is the main care issue: measured meals matter. Many shorthaired cats in shelters are random-bred domestic shorthairs with the same look and easygoing traits, so adopters may meet cats like this under either name.
