Felix the Cat is one of the most popular and recognized cartoon characters to come out of the silent era of American film history. Felix starred in animated short films, a comic strip and feature films since a prototype of the character first appeared in 1919. His films declined in popularity after the arrival of sound cartoons in the late 1920s, but the character has enjoyed a revival in recent decades and remains popular in merchandising of such items as clothing, stuffed animals and toys.
