The care of all pet hamsters is fundamentally similar, but there
are differences in feeding and housing needs. Dwarf hamsters are
sociable and are best kept with a cagemate of the same gender to
prevent loneliness, but Syrians are extremely territorial and will
kill other hamsters in their cage. Chinese hamsters can be kept in
pairs or groups but require a relatively large amount of cage space
for them to live peaceably. Although Chinese hamsters are very
placid in nature, female Chinese hamsters tend to become very
aggressive towards any male cagemates when pregnant
