Zazoo

Texts:
Whale Talk- Chris Crutcher
Samurai's Garden- Gail Tsukiyama
Tuck Everlasting- Natalie Babbitt

Statement:
The poetry interspersed sheds valuable light onto the relationship between Zazoo and Grand-Pierre, especially because some of the poems were written only by G-P, some together, and some only by Z. We see through the poetry how Z has grown up and become separate, although obviously still attached, from G-P.

Question:
What is the significance of the Duchess (the wife of the Doubtful Duke) having, like Zazoo, a cat that decided not to roam? Zazoo's sad grey cat provides her with solace, but what is the purpose of introducing another cat? Does this personally affect Zazoo? Especially when it comes from someone so unexpected?
