The smallest one you can find!
I think a Campbell's Russian Dwarf hamster
No best not to even attempt that trust me!!
Well, the hamster should be very active and running around the cage they have at the pet store. If the hamster is in the corner or is in the igloo house, then that may not be the best choice. For example, the hamster could be on the hamster wheel, that's a good choice!
6.5-7 inches is a good size for a 4 inch dwarf hamster. If the wheel is too big your hamster will be fine. It is when the wheel is too small that it becomes a problem.
A cage, bedding, running wheel, water bottle, food.

about big will a dwarf hamster grow about big will a dwarf hamster grow about big will a dwarf hamster grow
there is no such thing but if you mean a roborovski hamster yes its a dwarf
There is lots like, Syrian, Chinese dwarf hamster, Campbells dwarf hamster, Robo dwarf hamster, Russian hamster. My favorite, is the blueberry campbells dwarf hamster and the Syrian hamster. They are the sweetest and easy to hold. NOT THE ROBO"S!!!
You probably don't see your hamster when she or he climbs. If you just added something new into your cage, your hamster will be confused because it isn't used to anything new.
No, not everything, they need smaller cages - preferably plastic ones as dwarf hamsters can sometimes fit through the bars. A smaller wheel too, a hamster can hurt itself if its on a wheel that is too big.
