The British Shorthair descends from the domestic cats of Britain, with a stocky, round-faced build and one of the densest coats of any breed. The classic blue coat with copper eyes gets the attention, but the breed also comes in many other colors and patterns. Adults are heavy-boned, commonly 7 to 17 pounds, with males on the larger end, and they fill out slowly, often not reaching full size until around age three.
In a Denver home, a British Shorthair's calm manner is the main draw. Many follow their people from room to room, watch instead of climb, and dislike being carried. Plan for weekly brushing, measured meals to head off weight gain, and regular vet visits that include heart and kidney checks. Cats vary, so a quiet, easygoing nature is common but not guaranteed.
