Subaru has begun living with a cat as a roommate. He realizes he's run out of cat food and goes to a pet shop to buy more, but starts to panic when he's surrounded by creatures he's never been around before. Then Nana, a shop employee, starts to talk to him, asking him questions about the cat's name and age. Subaru then realizes he hadn't thought of a name for the cat yet. Nana tells him that he should give the cat a name because it's his family now, so Subaru tries to think of one, but nothing good comes to mind. As he's pondering, he comes across a book in his room called "The Moon and the Sun"...
Mom, watching the kitty 
is making me hungry, too.
Mama, vom Zuschauen
hab ich auch Hunger gekriegt.
Mamá, ver al gatito hizo
que me diera hambre.
Mamá, ver al gatito hizo
que me diera hambre.
Maman, il me donne faim,
à force de le regarder.
Mamma, adesso che ho visto il gattino,
 anche io ho fame!
Mamãe, ver o gato me deixou com fome!
Мама, я тоже проголодалась, 
глядя, как эта кошечка ест.
