The voice of A. Flea is uncredited and was provided by Sara Berner, except for the character screaming "T-Bone!" which was done by Mel Blanc. Blanc also performs the voice of the dog and the cat. As usual, Arthur Q. Bryan is the voice of Elmer. A. Flea would make another appearance in 1947's A Horsefly Fleas, directed by Robert McKimson, in which the "A" in the flea's name is revealed to stand for "Anthony".
