1st siberian mouse

The Siberian mouse, also known as the Siberian hamster, is typically referred to as *Phodopus sungorus*, or the dwarf hamster. It is a small rodent native to areas in Siberia and surrounding regions. This species has become popular in the pet trade due to its small size, friendly disposition, and interesting behaviors.
