The American Shorthair descends from working cats that traveled with European settlers to guard ships and grain stores from rodents. Pedigreed since the early 1900s, the breed is medium to large, usually 6 to 15 pounds, with a broad face, full cheeks and a dense, hard coat in dozens of colors. Silver tabby is the best-known look. Males are bigger than females, and cats can take three or four years to fill out.
Most are easygoing and quiet, happy to keep you company without demanding attention, and many love hunting-style play. Shedding is moderate, so a weekly brush is plenty, with a heavier shed in spring. Most shorthaired cats in the US are random-bred domestic shorthairs with the same look, so you may meet cats with these traits under either name, and a cat's own personality matters more than its label.
