Felix the Cat was a cartoon character created during the sulent-film era of the 1920s. Felix was the first cartoon character to become a large enough theatre draw just for himself.
There is dispute to the origin of Felix the Cat, whether he was from the creation of Pat Sullivan, the owner of the Felix character, or American animator Otto Messmer, Sullivan's lead animator.
In the 1920's, the Felix character gained sudden popularity. Felix got his own comic strip, drawn by Messmer and merchandising Felix goods became hot.
By the late 1920's, Felix popularity faded, just before the start of sound cartoons. In 1953, the Felix cartoons were airing on American TV with a redesigned character look.
The Felix the Cat cartoon available here are from the original 1920's.
