A "Library Cat" is a cat that lives in a library, often serving as a mascot or companion for visitors and staff. These cats can help create a welcoming atmosphere, making the library feel more inviting. They may also help reduce stress for patrons, as interacting with animals has been shown to have calming effects. Many libraries around the world have adopted cats, and some even have specific programs to promote their presence. Famous examples include Dewey Readmore Books from the Spencer Public Library in Iowa and Library Cat from the New York Public Library. These cats often become beloved figures in their communities.
