Hello and thanks for researching your question!
This is a pretty interesting variety of Hamster...they are very social and can
get along in groups. There are a few caveats:
1) You must never take them out and handle them separately. Dwarf Hamsters recognize each other by Scent. Separating them breaks the scent bond.
2) In mixed-gender groups, there can only be one male...dominant animals will starve or kill "extra" males.
3) Groups of bachelors can "set up house" by choosing a weak male and castrating him. He then plays "Mom". These eunuchs are never as healthy as the rest of the Gang, and can look shrunken or "worried".
Although some animals might not be very coordinated and may try navigating tubes in the way you describe, I am concerned about his falling down at other times. To know for sure what can be done about an ear infection (yes, a possible cause), he would have to be examined by a veterinarian who knows how to handle Hamsters and prescribe safe treatments:Look for exotic mammal vet here
Many Hamsters are born with developmental defects that make themselves known many weeks or even months after purchase.
Paper litter is best, XXXXX XXXXX before things get urine-wet is fine. You should consider using a dilute bleach solution to wash the plastic surfaces, since it is most prone to bacterial or fungal colonies that can kill your pets. You would have to take the cages apart and wash them thoroughly, followed by a good deal or rinsing.
Aspen wood bedding is OK...but it is more dusty (and may jam up your vacuum).
These animals eat seeds, grains, insects and small berries. Most Hamster mixes contain those green hay pellets...but most Dwarf Hammies do not eat them. Supplement the regular diet with whole grain cereals (non-sugared types...original GrapeNuts, Cheerios, Chex), multi-grain bread, boiled egg (with the shell left on!), loose Timothy Hay, and some dried cranberries.
If you are handling these guys as pets, then you really should have a separate cage for each one by the time they are fully mature (6-8 months).
