Whether a hamster will get cold if it only uses paper cotton in winter depends on the location. If it is in the cold north without any measures to keep warm, it will definitely be cold. If it is in a warm coastal area, the hamster will not get cold. In the central area, cotton production alone is not enough. We also need other means of heating.

Tips:

Hamsters are afraid of both cold and heat. When winter comes, we must do a good job of keeping warm, and when summer comes, we must do a good job of preventing heatstroke.
