Lisa keeps a journal of her new kitten's first year.

Lisa decides to start a journal to record the first year of her new kitten's life. On the left-hand page is a printed journal entry, on the right is a drawn journal entry along with a calendar month of days, starting from March. Covers the development growth of a kitten as well as annual activies and holidays occurring throughout the year (e.g., a camping trip in July, the new school year in September, Halloween, Thanksgiving, Christmas, New Year's, Valentine's Day -- until it's the kitten's first birthday.

End notes suggest activities revolving around the math concept of "calendar time".
