In Chinese tradition, there are indeed some strange taboos regarding keeping cats, mainly stemming from folk beliefs and legends. Here are some of them:
1. Do not place cats under windows: People believe that placing cats under windows will expose the house to attacks from evil spirits.
2. Don't talk about cats at night: In some places, people believe that talking about cats at night is unlucky because it may attract evil spirits or bring misfortune.
3. Do not leave dead cats in the house: People generally believe that dead cats bring bad luck, so once a cat dies in the house, it should be disposed of immediately.
