Little Roquefort is an anthropomorphic brown mouse who appeared in several Terrytoons shorts.
The Little Roquefort cartoons were directed by either Connie Rasinski (who did the first) or Mannie Davis, both of whom also did Gandy Goose & Sourpuss, Heckle and Jeckle and all the other Terrytoons stars. Both Roquefort and Percy were voiced by Tom Morrison, who also wrote for Terrytoons (and was the voice of Mighty Mouse's adversary, Oil Can Harry). A dozen and a half were produced during the first half of the 1950s.
His last appearance was No Sleep for Percy (released March 1, 1955).
Roquefort and Percy continued to appear as part of the general Terrytoons mix on CBS and in packages of cartoons syndicated to local stations for a long time to come. But those cartoons ceased being aired many years ago.
