Cats crawling into bed is not a good habit. This is because they shed fur, which not only gets on the bedding but can also become a source of germs, harming the health of both the owner and the cat. 
How to deal with a cat that loves to crawl into bed:
1. When a cat has a habit of crawling into bed, it is recommended that the owner correct it in time. Shout loudly to make the cat stop, chase the cat off the bed, or gently pat its head or buttocks to make it learn from the mistake and not develop this bad habit.
2. Owners should train their cats to sleep in their own cat beds. They can prepare a warm, soft cat bed for their cats and place it in a warm, quiet, and well-ventilated place.
3. When the weather is cold, put some warm things in the cat's bed to make it comfortable. Then the cat will be willing to stay in the cat bed and will no longer covet the owner's warm bed.
