In this chapter, we learn about the different types of diseases that cats can suffer from due to their excessive breeding. First, we're introduced to the concept of estrus, which is the breakdown of a cat's reproductive system. Estrus can lead to many diseases, including testicular and prostate cancers, and can also lead to anxiety and other problems. Examining the cat, zhixing notices that the cat is homesick, so he brings it back to his house. The cat is excited to be reunited with its owner, and zhixing tells him to call it "the band" instead of "the crushed ice" .
