World's Best remains my favourite kitty litter, not only in terms of its clumping and odour-reduction capabilities, but also because it's safe—it's made of corn—and sustainable. It works way better than tofu litter (which I've tried as well) and doesn't scatter all over the place like regular sand or pine litter. I wished the larger size of this litter was in stock, but had to get this smaller bag to tide me through for now.
