Interesting fact about Copycat
While we keep cats as pets today, during medieval times the term “cat” was used as a term of contempt for another person. The origin of the idiom “copycat” comes from 19th century Maine, when Constance Cary Harrison wrote in her 1887 memoir Bar Harbor that “Our boys say you are a copy cat, if you write in anything that’s been already printed.”
