Elaine

 is an elderly woman who Cat talks to in Cat Makes the Elderly Laugh and Cat Teaches the Elderly. She does not respond to anything Cat says to her. She lives in a nursing home with Bill and Parnell just down the street. Cat tries to make her laugh by pretending they're going to rob a bank together, but it doesn't work and she only gives her a confused look. She also reads her jokes from the 20th century joke book, but she does not find that funny either, possibly because Cat did not read the entire joke.
