I use the Wee Wee Pads from Jeffers.com. My ferrets have about a 90% accuracy as long as I pick the pads up once a day. The website that was asked about is: http://www.slippypad.com/. I have not used these because I get a good deal from Jeffers. The problem with the Wee Wee Pads is that they have to be taped against the wall or corner. Otherwise, the ferrets will take off with the pads and use them for nesting. By the way, the pads are cleaner for me as the ferrets are not digging in litter anymore. Of course, we do not have ferrets because we want totally clean houses! Dooks, Nancy and the fuzzies [Posted in FML 6024]
