How do I stop my Twin cats fighting each other ?

Hi! Meet my kitty nugget and goose nugget . They are a twin Cats , kitty is a girl and goose is a boy. They are both precious , sweet and playful . They will love chasing the red dot of a laser pointer forever, or shadows of your hands on the wall.
They’re both our excellent morning alarm clocks 🥰
