Things You'll Need
- A dwarf hamster
Instructions
Turn the hamster over so you can see its belly. You may have to hold it firmly with one hand so it doesn't flip over.
Look for nipples on the hamster's chest. There will be two rows of nipples on a female, and they are particularly hard to see on dwarf hamsters. You may use your fingers to feel for nipples on either side of the rib cage. The male dwarf hamster does not have nipples.
If you can't see or feel any nipples, examine the region around the hamster's anus. There will be two holes at the base of the dwarf hamster's belly, the lower hole being the anus and the upper hole leading to the sexual organs. In female dwarf hamsters, these two holes will be very close together, sometimes appearing only as one hole. In male dwarf hamsters, the two holes will be spaced further apart.
Other identifying features of a male dwarf hamster are the more rounded genital area (where the testicles are located) and a scent gland located mid-belly. The female dwarf hamster will have a more pointed genital area, and the sexual organs will be more inward-facing. The male dwarf hamster has smaller sexual organs than the female, and the area will not look as swollen.
