Compared to most shorthair breeds, British Shorthairs are relatively calm cats when they mature. They are easygoing in nature and talk infrequently. Very affectionate, they become quite attached to the people they own. British Shorthairs are easily trained and very adaptable. They seem to get along well with all human members of the household, regardless of age, but are usually not fond of being carried. British Shorthairs are not known for being acrobats and can tend to be clumsy at times. No breed specific, health related problems plague the British Shorthair. These are sturdy, dense-coated, purring, teddy bear cats with large round eyes. Another thing that draws people to the British Shorthair is their size. Although they are not huge like the Maine Coon, they are a medium to large cat. They are a slow maturing breed and do not reach their full size until three years of age. Mature males average 9 to 17 pounds, and mature females average 7 to 12 pounds. Although most people think of them as being blue cats, they come in a number of colors and patterns.
