Описание классов с использование ООП

На сколько корректно примерное описание классов?

public static void main(String[] args){
    Animal cat = new Cat(3,"Брсик");
    Animal dog = new Dog(5,"Вульф");
    List<Animal> myAnimal = Arrays.asList(cat, dog);
    for (Animal animal : myAnimal) {
        cat.eat();
        dog.eat();
    }
}
public interface Animal {
    int getAGe();
    String getName();
    void walk();
    void eat();
    void sleep();
}
public abstract class Canidae implements   Animal {
    private final int age;
    private final String name;
    public Canidae(int age, String name) {
        this.age = age;
        this.name = name;
    }
    public int getAGe() {
        return age;
    }
    public String getName() {
        return name;
    }
}
public abstract class Felidae implements Animal {

    private final int age;
    private final String name;
    public Felidae(int age, String name) {
        this.age = age;
        this.name = name;
    }
    public int getAGe() {
        return age;
    }
    public  String getName() {
        return name;
    }

}
public class Dog extends  Canidae {
    public Dog(int age, String name) {
        super(age, name);
    }
    public void walk() {
    }
    @Override
    public void eat() {
        System.out.println("Хрум");
    }
    public void sleep() {
    }
}
public class Cat extends Felidae {

    public Cat(int age, String name) {
        super(age, name);

    }
    public void walk() {
    }
    public void eat() {
        System.out.println("Ням");
    }
    public void sleep() {
    }
}
