Conversely, in some parts of medieval Europe, cats—especially black cats—were sometimes associated with witchcraft and superstition.
Ironically, the fear of cats at that time contributed to the increase in the rodent population, which may have worsened the spread of diseases.
Over time, however, society's view of cats evolved again, and they came to symbolize independence, mystery, intuition, and emotional sensitivity.
If we imagine what a symbolic prediction in the style of Nostradamus might mean, it would probably focus less on literal fortune and more on spiritual or psychological outcomes.
Those who have a cat at home often experience unique emotional benefits.
Cats are independent but affectionate creatures. Unlike dogs, which are generally expressive and eager to please, cats form bonds that seem selective and intentional.
This can create a deep sense of trust between humans and animals.
A person who wins the affection of a cat may feel chosen, which subtly increases self-esteem and emotional security.
Furthermore, scientific studies support the idea that owning a cat can positively influence mental health.
The simple act of petting a cat can reduce stress levels by lowering cortisol and increasing serotonin and dopamine—chemicals associated with happiness and relaxation.
The rhythmic purring of a cat, typically between 25 and 150 Hertz, has been studied for its potential therapeutic effects.
Some researchers suggest that these frequencies may promote tissue healing and reduce anxiety.
Therefore, if someone claims that Nostradamus predicted that "those who have a cat at home will live in peace," the statement is surprisingly consistent with modern psychological findings
