Hamsters are mammals which belong
to the rodent family.
There are many species of hamsters but only
5 species are
widely kept in captivity as pets.
Hamsters are nocturnal,
sleeping during the hot days and waking in
the cooler evenings. They have very poor eyesight
but a keen sense of smell and excellent hearing.
