There may be many reasons why cats like to scratch their shoes. Cats are born with curiosity and desire to explore. They are particularly sensitive to moving objects and sounds, and their shoes will emit sounds when they move. The sound and vibration attract cats to the mood of chasing and catching.

The cat may also feel comfortable and at ease because of the familiar smell. Lying on the shoes can relieve the cat's anxiety. Cats view the owner's shoes as a way of socializing and trying to establish a closer bond with the person.

Cats’ possessiveness and territorial awareness also have certain factors. They may think that their owner’s shoes are also part of their territory.
