I found an interesting New Yorker article about a new book being published based on a “lost” Potter work about a cat: “The Tale of Kitty-in-Boots,” which she had begun and abandoned two years earlier, in 1914. Several manuscripts of the story were discovered in 2013 in the Potter archive at the Victoria & Albert Museum. Read more here. Beatrix Potter complained to her publisher, "I do not draw cats well." I disagree and think her original drawing is quite charming.
