A sleepless night (1940)

A family of mice who live inside of a wall are trying to sleep, but Mom mouse is being kept awake by a dog snoring in the room outside of their hole. She wakes up Pop mouse, and has him go out to try to stuff cotton in the dog's mouth. Later, Pop Mouse goes out again to find some food. He finds a large piece of cheese, but he encounters some problems in trying to bring back enough for anyone else to eat.
