This wall calendar lets you enjoy the changing seasons with cats. The soft, gentle illustrations are original drawings by illustrator Sayo Koizumi, a cat lover herself.

The theme of the 2026 edition is "The Cats of the Koizumi Family." The calendar is packed with the daily activities of the four unique felines in the Koizumi household.
The lines, date numbers, and month numbers are all meticulously hand-drawn, creating a relaxing and comforting design.

The back of the December calendar includes a column about the arrival of a new kitten! This column is about the new kitten who arrived at the home while the 2026 illustrations were being drawn. Enjoy the daily lives of these four unique cats.
