First prepare a clean cat's nest for the cat, then put a blanket in the cat's nest, and put it in the cat's nest when the cat sleeps. If you repeat it many times, the cat will develop a habit. You can also put it in the cat's nest. Put some toys that it usually likes in it, so that when the cat is tired from playing in the bed, he will go to sleep directly. It is best to choose a softer material for the cat nest, so that the cat will like the cat nest more.
