Russian Blue Cat

　　Owners should promptly correct the habit of cats crawling under the quilt and not let them develop bad living habits. Cats should be made to sleep in their own cat beds, becoming well-behaved and obedient after training. To prevent cats from crawling under the quilt, owners should first prepare a soft, warm cat bed or cat house, placing it in a warm, quiet, and well-ventilated area. In winter, owners can place hot water bottles inside the cat bed or use bulbs to provide light and warmth, making the bed cozy and comfortable so the cat feels secure and comfortable staying in its own bed instead of coveting the owner's warm quilt.

　　Additionally, when an owner notices the cat trying to crawl under the quilt, they must not indulge or pamper the behavior. The owner should immediately stop and correct it. They can scold the cat loudly to make it stop, drive the cat off the bed, or gently tap its forehead or rump as a warning. Pet cats are very clever and sensitive to the owner’s attitude and behavior. As long as the owner’s words and actions are clear, the cat can quickly break the bad habit of crawling under the quilt. (Source：PetsZone)
