Library cats are felines that live in libraries, providing companionship and comfort to visitors and staff. They often help create a welcoming atmosphere, making the library feel more like a home. Many library cats have their own unique personalities and can often be seen lounging among the books or greeting patrons. These cats can also serve practical purposes, such as controlling pests like mice. Some libraries have adopted cats as part of their community outreach, promoting literacy and encouraging children to read. Famous examples include Dewey Readmore Books from the Spencer Public Library in Iowa and Library Cat from the New York Public Library.
