I'm considering owning a dwarf hamster (a campbell's or winter white) and if i did this they would likely be housed in a barney cage, since that's what i already have, but I'm concerned that the bar spacing might be too big and a small dwarf might be able to wriggle through! If anyone has had a dwarf in a barney then help would be greatly appreciated, thank you!
