There is one person, though, who is not happy with the mouse's new digs. Mr. Billings is not pleased there is a mouse in the house and sets traps to get rid of the new guest. But Mr. Billings' kids think a mouse in the house is cool, and they convince him to be their friend. They feed him, play with him, and even warn him about where the traps are set. Based on a true story, Mouse in the House tells the tale of one little mouse who lives on, eager to entertain and educate. Just as life is full of lessons to learn, this story offers topics for guided discussion, including fear, empathy, acceptance, and rightness.
