鉴于此课程; 我将如何迭代它包含的方法？

class Animal {
    constructor(type){
        this.animalType = type;
    }
    getAnimalType(){
        console.log('this.animalType: ', this.animalType );
    }
}

let cat = window.cat = new Animal('cat')

我试过的是以下但没有成功:

for (var each in Object.getPrototypeOf(cat) ){
    console.log(each);
}
