Methods to train a cat to sleep in the nest:

1. When the cat wants to go to bed, the owner should give it a serious "no" command. I can only go to sleep in the nest.
2. When the cat feels that the cat's nest is not warm in winter, it will naturally stay in a place that it thinks is warm. You should promptly put a thick blanket or hot water bottle on the cat's nest, and then guide it to sleep in the nest.
3. Observe where the cat often sleeps, and then move the cat's nest to a place where it likes to sleep, and it will take the initiative to sleep in the cat's nest.

4. Pretend to give the cat nest to other pets at home, so that the cat will keep the cat nest and stay in it because of its strong possessive desire.

5. You can sprinkle some mint in the cat's nest. The cat likes the smell and will stay in the cat's nest obediently.
