This is a superstitious belief, and there is no scientific evidence to prove a direct link between the appearance of cats and death. We should trust science and rational thinking, dispel superstition, and establish a scientific worldview, outlook on life, and values. When facing challenges and difficulties in life, we should actively seek solutions rather than pinning our hopes on illusory predictions or intervention from supernatural forces.

Encountering a cat is not an omen, but a common occurrence in life. Cats are common pets, and they can be seen in every corner of cities and countryside. Don't be overly superstitious or reliant on such omens; instead, trust science and rational thinking, and view things from a scientific perspective.
