Calm British Shorthair, used to apartment living

Our British Shorthair cat, Oliver, has lived with us for almost three years and has always been an extremely peaceful companion. He's not a hyperactive cat who jumps around the house. He prefers to quietly observe what's going on around him and spend time near people without necessarily demanding constant attention. Every evening, he comes to settle near the sofa when someone is watching a movie and stays there simply to be close. He mainly eats high-quality kibble and has never shown any destructive behavior in the house. The reason we need to find him a new family is due to a job relocation to another country where the conditions for traveling with a pet are becoming very complicated. We hope to find someone who appreciates cats with a calm and stable temperament.
