Trying to remember title of a children’s fiction book set in New Orleans. Read in the 80s. One rich white fluffy groomed cat and one thin scruffy chimney sweep cat. Illustrations in black-and-white. Title may have been in blue foil. White cat may have lived on St. Charles Avenue.
Illustrations may have been somewhat similar to Black and White illustrations in Roald Dahl’s books. Shaded gray, a little messy.
