Gaffer is the bedraggled, one-eyed cat who was frequently seen hanging around backstage in the later seasons of The Muppet Show. The cat was introduced in episode 419. Performer Kathryn Mullen spoke of the characters creation in a 2013 interview: "Jim wanted a cat, and he said, “Give that to her, let her practice.” That was his way of making it easy for me to get really used to the monitor and following things and it was a little training exercise. It was very effective." Gaffer also appeared in The Great Muppet Caper and would later make a background cameo in Muppet Treasure Island and also made a background appearance in Muppets Tonight Episode 101: Michelle Pfeiffer.
