Bored and annoyed, why did Dingdong like to live with Nobita?

(1) Xiong is kind and thin, and Pang Hu is too greedy, eager and fierce. With him, the cat will be tortured to death. Dingdang cats and big bears spend more time together and have complementary personalities.

(2) Bears are simple-minded, and cats can find a sense of accomplishment in ascension.

(3) Bear is easy to shake, not as proud as Ah Fu. As long as you help him solve the problem, there will be gongs to eat.
