Note: I read this book in English, so I wanted to write my comment in this language.
Firstly i have to say that I was very impressed that their loyalty.
If we look at the story... There is a man named James. He is also the author of the book... At the beginnig of the story, he struggled with his personal and health problems, with people who just care about his appearance and doesn’t care personality. Unfortunately even his family didn’t care about their son. They totally ignored him. As if James wasn’t their son...
And the story has entered a very nice turn! James met a street cat, with has blue big eyes, blonde hairs, when his life was in a very difficult time. The cat was a very loving and loyal cat. James took his to his home and started living together. They loved each other and were connected.
James overcame his problems thanks to Bob in time. The cat was always with him even in the worst case. Bob never gave up being with James. And that was the real love and loyalty between two alive... : )
