Thanks, dornen. I have already looked at the CSE wheels and I can't find them on amazon (the only online place I shop) or if I do find them on another website then they are WAY too expensive. I would really like to have one of those in her cage, but my parents perfer nothing over 12 - 15 dollars. And 15 dollars is REALLY pushing it. I don't think they will go over 13 or 13 dollars, but thanks for the suggestion
