The American Shorthair descends from working cats that crossed the Atlantic with European settlers to keep rodents off cargo, then guarded barns and homesteads. In the early 1900s the sturdiest of them became a pedigreed breed. The result is 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 as the classic look.
Many American Shorthairs are easygoing, quietly affectionate and content to keep an eye on household life without demanding constant attention. They usually enjoy chase games and tend to gain weight without them. Plenty of shorthaired cats in Boise homes are random-bred domestic shorthairs with the same look, so adopters may meet cats with similar traits under either name. Each cat's personality still varies.
