Why is peters cat important to him?

Please provide me with more context! I need to know who "Peter" is and what cat you're referring to.

For example, tell me:

* Who is Peter? Is he a character from a book, movie, or TV show? Is he a person you know?

* What is the cat's name?

* What do you know about Peter's relationship with the cat? Does he seem particularly close to it?

Once I have this information, I can help you understand why the cat is important to Peter.
