Problem 3: Noisy Cat (100pts)

Problem

More cats! Fill in this implementation of a class called NoisyCat, which is just like a normal Cat. However, NoisyCat talks a lot -- twice as much as a regular Cat!

We may change the implementation of Pet and Cat while testing your code, so make sure you use inheritance correctly.

更多的猫！请完成这个名为 NoisyCat 的类实现，它就像一只普通的 Cat。然而，NoisyCat 说话很多——是普通 Cat 的两倍！

我们在测试您的代码时可能会更改 Pet 和 Cat 的实现，因此请确保您正确使用了继承。

class NoisyCat:  # Dose this line need to change?
    """A Cat that repeats things twice.

    >>> chocola = NoisyCat('Chocola', 'Minazuki Kashou')
    >>> isinstance(chocola, Cat) # check if chocola is an instance of Cat.
    True
    >>> chocola.talk()
    Chocola says meow!
    Chocola says meow!
    """

    def __init__(self, name, owner, lives=9):
        # Is this method necessary? If not, feel free to remove it.
        "*** YOUR CODE HERE ***"

    def talk(self):
        """Talks twice as much as a regular cat."""
        "*** YOUR CODE HERE ***"
