All is quiet in the city as beings big and small find shelter from a snowstorm, except for one tiny squeak. It's baby Badger, a newborn kitten with no momma to carry him to safety. He's cold and so alone—until a helpful human finds him and brings him to the warmest place on earth: Fosterland. There, baby Badger is still an orphan, but he has a cozy house filled with stuffed animal friends who become his family. With Miss Moose, Teddy, and Monsieur Crocodile by his side, Badger has everything he needs. Then, a cat named Mama Mia and her five kittens join him! And Badger isn't sure what to think of his new roommates. They do all sorts of confusing things: the kittens eat from their mom instead of from a bottle like him, and they lick each other. So odd! But as Leeni, Mia's sassy and bold kitten, begins to befriend Badger, he'll have a decision to make—stay in his cozy, safe space with his stuffed animals, or risk it all for a friendship with his potential new pals.
