After doing more research I have found that Kitty Litter... IS ...Bentonie Clay!!!...just granuals, it hasn't been pulverized into powder, just make sure that you buy 100% kitty litter and that there are NO additives, (like perfume, chemicals to form clumps...etc.)...so that would mean the really cheap stuff at the dollar store. I have learned so many facts about this clay...The various names it is called...many of its uses...how it is packaged...on and on!!!
