Dogs are not the only domestic animals who sometimes must learn to adjust. In Won Ton (Henry Holt, 40 pp., ages 4-8) award-winning children’s book author Lee Wardlaw and Russian-born illustrator Eugene Yelchin tell the story of Won Ton, a cat rescued from a shelter who strives to settle into his new home. Accompanied by Yelchin’s winning drawings, the willowy Won Ton tells us his story – in perfectly formed haiku.
