[cypher]

I think it's a bit flimsy compared to a wodent wheel but I haven't had one of those so not sure.

Another thing to watch out for is climbing on the spindle, I'm pretty sure Zephyr was doing that with hers, not sure how else she was chewing the label off from the centre! It's seemed a bit dangerous to me & I think the safest enclosed wheel for a Chinese is the silent runner which doesn't have anything inside to climb on.
