===Social behavior===
[[File:Hamster fight.jpg|thumb|right|Hamsters fighting]]
Most hamsters are strictly solitary. If housed together, acute and chronic [[stress (psychological)|stress]] might occur,<ref name="Kuhnen, (2001)"/> and they might fight fiercely, sometimes fatally. [[Phodopus|Dwarf hamster]] species might tolerate [[siblings]] or same-gender unrelated hamsters if introduced at an early enough age, but this cannot be guaranteed. Hamsters communicate through body language to one another and even to their owner. They communicate by sending a specific scent using their scent glands and also show body language to express how they are feeling.<ref name="caringpets.org"/>
