The term 'CAT'S EYE, AT TIMES' can be solved by the four-letter word 'SLIT'. A cat's eye is a reflective device used in road markings and is made up of a central core surrounded by a series of concentric circles. At night, when illuminated by car headlights, the central core reflects back as a bright white light. The reflective material is also cut into a SLIT shape to increase the visibility of the cat's eye.
