Cats like to scratch your feet under the quilt because they want to play with you or think of your feet as prey. Because hunting is a cat’s nature, when a cat sees feet under the quilt, it will think that there is prey hiding under the quilt. It is inside, so it will treat its feet as prey. If it is not covered with a quilt, the cat will basically not scratch its feet. If you don’t like cats scratching their feet, you should stop the cat’s behavior in time to avoid being scratched by the cat.
