Tree tells Lucy that her family is moving away, and they decide to write letters. Lucy writes about her brother Brady, and how he is missing Tree's cat, Oatmeal. Tree writes about Oatmeal's strange behaviour and Lucy suggests that Oatmeal might be homesick. Then Oatmeal goes missing, Brady goes missing too, but is found curled up at a local store, with the owner's cat. Later, Oatmeal is found in Tree's old neighbourhood, playing with Brady. Tree lets Bardy keep Oatmeal. Oatmeal has five kittens. When Lucy goes to visit Tree in the holidays, she gives her one of the kittens.
