Who is Roger Dean Kaiser? What does his cat man want to express?

This article is a reading topic for the senior high school entrance examination in Guangzhou today. I've read it carefully. Try to answer it.

(1) What does the owner's name "Catman" mean? Is this a coincidence or a deliberate arrangement?

The name of the ship is "Catman", not the owner's name, and the title of the article is also "Catman". These two words can well sum up the whole story, which can be understood as "the story of cats and people", "people who love cats" and so on.

This was specially arranged by the owner of the cat, because the boat was definitely more than 2,500 yuan, and the check happened to be 2,500 yuan. It can be seen that the "Catman" was prepared for me by the old man.

(2) Finally, I said "I" know what I should do, so what is the practice?

I didn't see the words "I know what I should do" in the article, only "When I saw the name of the ship, I immediately decided it was it." This sentence is obviously that "I" understood the kindness of the old man and accepted it gladly.

There are many omissions in the original text you gave me. I hope my answer can help you.
