Why does Doraemon hate calling it civet cat?

Because Doraemon has no ears and its head and body are as round as a ball, it looks like a civet cat in the eyes of the Japanese, and Doraemon is regarded as a civet cat by others in many places in the TV version and the theater version. At this time, the picture will be like a civet cat, and you will feel very similar after reading it. Doraemon wants to prove that he is not a civet, but a cat robot, but the more anxious he is, the more people like to see him like that, so it is reasonable for friends to make fun of him, make him angry and strangers to misunderstand him.
