She was talking to me about hamster dividers. I have never seen them And never heard of them. I doubt you're going to find one Sarah, unless you search around ALOT and pay some money... I think it's best you just get another cage and another wheel. I have an extra bowl I could probably find and give to you. All you really need to but is the cage, wheel, and water bowl. And that'll probably be a grand total of $25-$30. Good luck!
