For Peace/Harmony
Fortune Cats that promote Peace and Harmony are often white, or are depicted with koi fish. Owls are also a common animal that represent peace, as the Japanese meaning for Owl directly translates to "without hardship".
Peace and Harmony luck refers to the favorable circumstances that bring a sense of emotional balance into one's life. This would mean being surrounded by less conflict, chaos and drama, to experience a sense of stability and predictability as well as allowing the individual to experience a stress-free life, with less anxieties and worry!
