Black cat enters the house, this proverb is widely circulated among the people and is often used together with "nothing comes without cause," making people feel that the arrival of a black cat heralds unusual events about to happen. However, is this an ancient superstition or is there some scientific or psychological explanation?

The black cat entering the house holds completely different meanings in different cultures: in traditional Chinese culture, the black cat (also known as the "Xuan cat") is often regarded as a lucky symbol for protecting the house from evil and attracting wealth, especially in some wealthy families where black cat ornaments are placed to pray for good luck. In medieval Europe, however, black cats were unfortunately demonized, associated with witches and bad luck. So, whether a black cat walking into your home is a blessing or a curse entirely depends on the cultural background.

Black Cats in the Long River of History: From the Altar to "Ominous"

The story of black cats is full of ups and downs, playing multiple roles in the long river of human history.

1. Ancient Egypt Worship: The Sacred Guardian

Tracing back to ancient Egypt, cats held a very high status and were considered sacred animals. According to Greek historian Diodorus Siculus, cats lived in temples and were carefully cared for, and even accidentally killing a cat could result in a death sentence. Cats were believed to be incarnations of the moon goddess Bastet, with the power to ward off evil spirits and protect homes and children. Archaeologists have even discovered a large number of mummified cats, demonstrating their status in the hearts of ancient Egyptians.

2. China's "Xuan Cat": Symbol of Exorcism and Wealth

Unlike the Western medieval view, in traditional Chinese culture, black cats have a more positive image. Ancient people called black cats "Xuan cats," believing that "Xuan cats are objects that ward off evil," able to repel demons and evil spirits and bring good fortune to their owners. There is even a saying, "Yellow-eyed black cats attract wealth, green-eyed black cats protect the house." Many wealthy families in ancient times chose to keep black cats or place black cat ornaments, believing they had spiritual powers and were auspicious for protecting one's home and attracting wealth.

3. European Medieval Stigmatization: Tied with Witches and Misfortune

Unfortunately, in medieval Europe, the fate of black cats took a sharp turn. Influenced by religion and superstition at the time, black cats were mistakenly linked to witches, black magic, and evil. People believed witches could transform into black cats to escape pursuit, or that black cats were messengers sent by the devil. This panic led to large-scale persecution and slaughter of black cats, with many innocent cats perishing. Some even say the spread of the Black Death was related to a decrease in black cats and an increase in rats. This negative image even affected part of modern Chinese cultural views of black cats, causing them to be seen as unlucky by some.

"Black Cat Enters the House, Nothing Comes Without Cause": Multiple Interpretations in Folk Sayings

This proverb is widely circulated among the people but its meaning is not singular. It can be interpreted in two main directions:

Interpretation One: Heralds "Bad Things" Will Happen

This is the first meaning many people associate with this saying. Under this interpretation, a black cat entering the house is seen as an ominous sign, indicating that illness, financial loss, or even death may occur in the household. This view may have been influenced by the medieval European superstition about bad luck from black cats and has combined with other folk beliefs such as "Cats bring poverty, dogs bring wealth, cats cover white cloth"—here "cats" sometimes generally indicate misfortune. Especially in some folk tales about "black cats jumping on coffins," black cats are linked to horror stories of corpse changes, deepening their ominous image.

Interpretation Two: Indicates "Something" Will Happen, Not Necessarily Bad

Another interpretation holds that "nothing comes without cause" does not exclusively refer to bad things but to unusual events—both good and bad. Under this understanding, a black cat entering the house can be seen as a "signal," reminding the homeowner that changes may happen soon. Combined with the traditional Chinese cultural meanings of black cats warding off evil and attracting wealth, the arrival of a black cat may also indicate improved fortune or coming good luck. For example, in Scotland, a strange black cat lingering on the porch is a symbol of prosperity; in Germany, if a black cat walks from your right side to left, it means good things are coming; in Japan, encountering a black cat is even believed to offer the chance of finding a dream love. Some even suggest black cats appear in certain places because they can "see" things humans cannot, and such places might have "unclean" presences, with the cat’s arrival being a form of suppression that is misunderstood as bringing misfortune over time.

Scientific Explanation: The Truth About Cat Behavior

Putting superstition aside, from a scientific perspective, cats entering homes is usually due to instinctual needs and habits:

1. Searching for Food and Water: The most common reason for stray or feral cats entering homes is to find food and water. They may be hungry or thirsty, smell food inside, or see food and water placed at the door and come in.

2. Seeking Shelter and Warmth: Cats look for safe and comfortable environments. Especially in harsh weather (such as cold winters with temperatures below 0 degrees Celsius) or when feeling threatened, they may enter human residences seeking shelter. Cats dislike change and prefer stable conditions but are also curious and will explore unknown surroundings.

3. Territorial Behavior and Exploration: Cats have a sense of territory and will explore their surroundings. A black cat entering a house might be patrolling its "territory" or simply exploring out of curiosity. They use scent marking and other methods to assert their presence.

4. Attracted by Stimuli: Some house cats might be attracted by smells, sounds, or lights at another home and accidentally wander inside.

5. Lost or Strayed: Some pet black cats that get lost may mistakenly enter strangers’ homes seeking help or shelter.

It is worth mentioning that some claims that black cats have special abilities, such as "seeing" things invisible to humans, currently lack scientific evidence. Cats do have better night vision and more sensitive hearing than humans, which may lead them to notice environmental changes more keenly, causing behaviors that seem "supernatural" but are normal animal behaviors.

Psychological Suggestion and the "Law of Attraction"

Besides folk sayings and scientific explanations, psychological suggestion also plays an important role in how people interpret black cats entering the house. If a person already believes black cats are unlucky, when a black cat enters, they may pay more attention to any misfortunes in life and attribute those to the cat’s arrival, creating a negative psychological loop. Conversely, if someone holds a friendly or positive attitude toward black cats, even some minor troubles may not be linked to the cat. This is somewhat like the "law of attraction": what you believe is what you are more likely to "see."

Frequently Asked Questions

• Q: Does a black cat entering the house really bring bad luck?
  A: From a scientific viewpoint, a black cat entering the house is a behavior driven by survival instincts and is unrelated to bad luck. Negative folk sayings mainly stem from historical superstition and misunderstanding. In traditional Chinese culture, black cats are often seen as auspicious and protective.

• Q: What should I do if a black cat enters my house?
  A: Stay calm and do not panic. If the cat appears healthy and friendly, you can try providing food and water. If possible, check if the cat wears a collar or any identification to find its owner.

• Q: Why is there such a big difference between Chinese and Western views of black cats?
  A: This mainly results from different historical and cultural backgrounds. Ancient Egypt and China both assigned a high status to cats and believed they had protective powers.
