When Mrs. Crump finds a yellow cat on her porch step, she tells the cat to “shoo.” She leaves the door ajar, however, and the cat slips into her home and into her life. As Mrs. Crump learns to care for the cat’s needs, she comes to appreciate the cat’s companionship as well. “Before you know it, you’ll be…wondering how you ever got along without [the cat],” Mrs. Crump’s new friend Mr. Henry says. Through colorful, playful illustrations, the story shows how cats make good company. Themes of stray animals, responsible pet ownership, and how animals can affect people’s attitudes are included.
