The quote reflects a profound sense of loss and absence experienced by the character. The cat, once a tangible presence in the character's life, has left behind a void that shapes their current reality. This "cat-shaped hole" symbolizes how deeply the presence of a loved pet can impact one's emotional state, suggesting that even in its absence, the memory of the cat lingers on. The character's perception of the cat transforms from a living being to a poignant reminder of what has been lost.

This theme of absence resonates throughout "A Tale for the Time Being," as it explores the connections between memory, existence, and loss. The narrative delves into how these connections can create a palpable sense of longing and emptiness. In this way, Ozeki invites readers to reflect on their own experiences of loss and the lasting impressions left by those who are no longer present in their lives.
