When I first gave Elliette her 15' chin spin she would run inside of it. Then she started running on the outside of the wheel (on top) sometimes and running inside the wheel other times. Sort of back and forth, in and out. Now though, she will only run on the top. Is there a need for concern with this or is this okay? Should I just move the wheel up so it sits just underneath the shelf above it instead of leaving some space? My only concern with that is that she will not be able to safely use the wheel at all from the ground level of her mansion. I tried to search around a bit before posting, but all I found were vague comments about some other chins doing this. I suppose I would just like to ensure it is okay behavior to condone and also if it is more of a health risk or an out-right indicator of such. She appears healthy, happy and hungry.
