The number of cat's eyes (reflective road markers) per mile of road can vary based on local regulations and road design. Typically, they are placed every few feet along the road, often around 100-150 feet apart in some regions. This can result in approximately 320 to 528 cat's eyes per mile, depending on the specific spacing used.
5280 feet to a mile. California stripes the road at 9 feet of white line for 15 feet of unmarked line. One cat's eye per stripe would mean 2203 per mile. Varies with installation and specific state regulations.
Cats eyes, also known as road studs or reflective road markers, were invented in the 1930s by Percy Shaw, a British inventor. Shaw came up with the idea after being inspired by the reflection of his car headlights in a cat's eyes on a dark road.

If you're referring to the objects in the centre of the road - that are sometimes called cats eyes, then it's reflected light. No cats were harmed in making them.
they reflect the light using the law of incidence
There are 5280 feet in a mile.
Cats eyes are used on a motorway to serve as a retroreflective safety device and as road markings. Amber cats eyes, in particular are used in the United Kingdom and Hong Kong and are placed along the edge of the central reservation.
