A Sick Day for Amos McGee (2011)

Amos McGee is a zookeeper who has bonded with the animals he takes care of. Each day, Amos spends a little bit of time with one of his friends at the zoo. He will keep the shy penguin company, run a race with the tortoise, and even read a bedtime story to the owl. When Amos is too sick to make it to the zoo, his animal friends decide they need to return the favor. This book beautifully demonstrates that friends come in all sorts of shapes and sizes. In Amos McGee's case, all sorts of species too!
