Rosemary Wells (born January 29, 1943) is an American writer and illustrator of children's books.
In 1968, Wells published her first book, an illustrated version of Gilbert and Sullivan’s A Song to Sing, O!.
It is about a young Japanese kitten who, in the beginning, is ostracized when she brings in sushi for her school lunch.
At the story's conclusion, she gains acceptance by hosting a school luncheon where everyone brings in food native to their family from around the world.
Many of the animal characters, such as those in Max & Ruby, interact with one another much as humans would, while others such as McDuff – a West Highland Terrier – take on a more realistic role as the adopted pet of a young couple.
