The idea that cats are messengers of the underworld is a superstitious belief and has no scientific basis.
In modern society, we should respect all animals and natural phenomena, and avoid using unscientific language and concepts to describe them. At the same time, we should also establish a positive, healthy, and egalitarian worldview and values to promote harmony and development in human society.
Cats don't see ghosts. Cats have excellent night vision and dynamic vision, so they can see tiny insects that humans can't. When a cat is staring at one spot without moving, it's probably just looking at a small insect.
