Why is night shift called cat-eye?

The term "cat-eye" is not a common name for the night shift. It's more likely you're thinking of "graveyard shift", which is often called that due to its timing, starting late at night and continuing into the early morning hours.

The association with cats might stem from their nocturnal nature. Cats are often active at night, which aligns with the hours of the graveyard shift.

However, there's no official connection between the term "cat-eye" and the night shift.
