Also, even though as a forum we don't impose cage sizes on people anyway (and I know many people would probably be unhappy with me having the opinion I'm about to state) I would much rather see a hamster that is loved, cared for and treated properly but in a slightly smaller cage than one in a massive cage that's just left to it and never bothered with (Not saying people with big cages do this but I have seen more than my fair share of people who do!).
If you can upgrade in the future then that's fantastic but if not, just make the most of what you have. The fact that you worried enough to post this just shows what a caring and responsible owner you are
