Well, I checked all of my local stores for pumice stones for my little guys and no luck. I basicly heard the same thing over and over again that the Chin population is just not there for it to be cost effective to carry them. So, I turned to my old friend "Ebay" and found them. From everything that I've read, it seems I am doing everything right except for not having the stones, so now they are on their way!
Thanks to you all for the advice!
P.S. I'ts 99 degrees outside!
Thank god for the super nice AC!
