The cat suddenly and frequently buries under the quilt may be caused by the cold weather, wanting to play hide-and-seek with the owner, or being frightened. You need to observe whether the cat's mood is abnormal. If there is any abnormality, you need to comfort the cat and let it go. The cat relaxes. If there are no abnormalities, you can prepare a warm and comfortable cat nest and blanket for the cat, which can reduce the chance of the cat getting under the quilt.
