Fanciers say the British Shorthair is the perfect household companion if you like an intelligent breed who is not too demanding. Brits are gentle giants with a touch of British reserve, particularly when you are first introduced. Once they get to know you, however, they become loyal, loving companions, as long as you are loving and loyal in return.
The more time, energy, and love you give them, the better your relationship with them will be.

Brits tend to be quiet cats, and it's amusing to hear tiny squeaks instead of hearty meows coming from those big, strong bodies.
They make up for that by purring loudly.

Brits enjoy keeping an eye on their favorite people, as long as it can be done from a comfortable lounging position. Brits are affectionate without being clingy and playful without being hyper, and tend to treat the entire family as their clan rather than bond with one special person.
They enjoy games and have a quiet sense of humor. But they also need room and time alone to be truly happy. Brits are not lap cats, preferring to curl up near you or sit beside you to be petted and stroked.

Once Brits have accepted the other feline members of their family, they get along well with little or no jealousy or fighting.
Confident and not usually intimidated, Brits can get along well with dogs if the right introductions are made and the dogs are compatible with cats.
