Hello,
I currently have the 6.5" silent spinner for my wee hammie... but I have seen him climb (he literally has to climb into it!) into it and then it doesn't move. He's just too small (bless his wee little legs!)
So, which is the best, and quietest, free moving wheel? I would prefer not to get a wooden one for hygiene and safety reasons (ie. splinters).
Thank you
