Just wondering if anyone here using this. I would like to know what kind you use and where to get it. I used the disposable ones but I think it's a waste of money. And then I tried potty patch thinking it would be better because I could just clean it. It was great at the beginning. Smeagol loved to go there but then after awhile he didn't want to use it anymore and I couldn't get the stink out. It's just awful. I've read about the washable one and want to know more about it. Thanks.
