Beth Fitzgibbons is a character in The Secret of NIMH. She is the farmer's beautiful wife and the mother of Billy Fitzgibbons. Although Mrs. Brisby once pointed out that Dragon was the farmer's cat, Beth is the one who is most seen with Dragon, such as when she scolds him for being "lazy" and tells him to go catch some of "those rats" out in the barn, and when she is about to let him into the house. She is voiced by the late Lucille Bliss.
