In this game, you will have to use your mouse to remind Jerry and Nibbles that rushing from one place to the other might cause too much rumbling. They will be recklessly running all around the house otherwise. You should make sure, however, that they do not make too much noise. To do that, click and hold whenever you need them to walk quietly on their toes. You might also need to take some extra care to ensure that the mice are always tiptoeing near any breakable object on the floor. If they don't do that, they will undoubtedly hit the object. Obviously, the clatter will not be well received by Tom. To keep track of Tom's sleepiness, you can use the Noise Meter that will measure the noise. Each time you disturb him, the meter will fill up a little. When the meter is full, however, the cat will wake up, and you will lose the game.
