Java reflection: Get inner instantiated field

I have an interface which looks like this:

public interface A {
    public interface B {
        public static final Cat cat = new Cat("Alice");
    }
}

Is there any way I can access the Cat object through reflection?

I have tried this:

Field catField = Class.forName("A.B").getField("cat");

But it gives me a ClassNotFoundException.

Thanks in advance!
