A shadow cat is a small filmy creature in the vague form of a domestic house cat. They are believed to be revenants or they may be living cats from another dimension.

They can only be seen from the corner of the eye, appearing as a shadow that quickly slips away when you look directly at it. They may also resemble a corporeal cat, but when you see one you're left thinking you saw something that wasn't there.
