Felines and Phantoms: Can Cats See Ghosts?

Throughout history, cats have been associated with the supernatural, and the ancients believed they had unique connections with the spirit world. In Ireland and Scotland, it was once thought that the Cat Sidhe or Cat Sith would steal a person soul before it was claimed by the gods after burial. Folk would perform watches called Feill Fadalach over the corpse night and day to keep Cat Sith away and use methods of distraction like using catnip. They also would not light fires near a corpse as they believed the warmth would attract the Cat Sidhe.

From a scientific point of view, we know that cats have sharper senses than we do. A cats’ eyesight is better than humans, and recent research suggests cats see ultraviolet light which humans cannot. Cats view things in just two colours, yellow and blue. We also know that cats can see in the dark, like a night vision camera. Their pupils allow more light in than ours do. Acting like little motion detectors as well our cats eyes have an inbuilt ability that picks up small movements invisible to the human eye.
