While Dr. Seuss won many awards for his work, he never won a Caldecott Honor.
The Caldecott Honor is awarded to illustrators of children's books, recognizing outstanding artistry. Dr. Seuss was primarily known for his writing and unique illustrations. He did receive the Caldecott Medal (the highest award) for "The Cat in the Hat" in 1958, but this award was for the book as a whole, not specifically for the illustrations.
It seems you are a bit confused! Let me know if you'd like to know more about the Caldecott awards or Dr. Seuss's other accomplishments.
