just a little update! Star has now started to use the wheel like she used to use her old one. I was really hesitant on placing the old wheel back into the cage due to the instability issues with it I was afraid of her getting hurt on the old one (a silent spinner). I am so thankful for all your help and I would definitely recommend this wheel if you can get your hands on it. For the concern of her not being able to spin the wheel this wheel actually spins super easily and she seems to be running much faster on this one but I really appreciate the concern
