I Have to Russians - the wheels they have are OK but they can get their legs caught- in other words they have spaces inbetween- I have 2 robos they have silent spinners I tried the dwarfs in them last night and the wheel seemed a bit small for them - I think they are the 5.5 size the mini- but they fit fine backs were straight they a re not cheap and I need 2 - and am headed for the store in about an hour- they did not seem to know jhow to use them but it could have been becasue they were new to them ?

Good for you for knowing that the wheels with spaces are dangerous and for replacing them. Just so it's not a surprise, those Silent Spinners are quite noisy. Unless you have two cages, one wheel will do. I have a regular sized hamster and she runs just fine on the 6-inch wheel. She took two days to figure out the wheel.
