The main food of hamsters is plant seeds, like nuts, as well as plant stems or leaves, and occasionally eat bugs. In addition, it needs a lot of water, and it is not enough to eat water by eating plants. Most hamsters do not hibernate and live in storage in the winter. A small number of species will enter a less active quasi-wibernation state in cold weather conditions.
Hamsters are mainly active at night, with poor eyesight and can only be blurred and discerned. The color can only distinguish between black and white. Some breeds of hamsters have become popular pets in recent years because they are close to people.
