Cats sleeping with people can easily cause allergic reactions or skin diseases in some people. If the owner catches a cold, it may be transmitted to the cat. Moreover, cats lose hair, and people can easily inhale the food into the respiratory tract or lungs, which will harm health in the long term. Therefore, it is best to let the cat sleep in the cat's bed. This can also prevent the owner from crushing the cat when he turns over in sleep, and can also prevent too much cat hair from sticking to the bed.
