Why can't we have a cat at home? Bad luck.

Whether cats are lucky or not is related to people's beliefs, culture and personal feelings. Some people think that owning a cat will bring bad luck, while others think that owning a cat is a lucky thing. There may be many reasons for this idea.

First of all, cats are regarded as unlucky symbols in some cultures. In some religions and folklore, cats are considered to be associated with darkness, evil and disaster. This concept may spread to modern times, making some people express resistance to owning cats.

Secondly, cats are independent animals, and sometimes they show autonomy and independence, unlike dogs, which show strong dependence and obedience to human owners. This may lead some people to think that owning a cat will make them lose control of their family or personal life and feel unlucky.

In addition, cat hair and cat excrement may cause allergic reactions, leading some people to have a bad impression on cats. They are afraid that they or their families are allergic to cat hair, so they refuse to have a cat.

Finally, personal experiences and family traditions may also affect people's views on whether cats are lucky or not. If someone has had an unfortunate incident related to owning a cat, it may make them have an unlucky cognition of cats. Similarly, if someone's family holds an unlucky view of keeping cats for generations, then they may follow this belief.
