Simon has unknown allergies. At the moment we are trying to get him on an all natural cat litter or at least one that is good for sensitive cats. I have been trying out the Swheat scoop brand but I find that it stinks. I clean the litter box twice a day but still find that when they do a number 2 it's like a bomb went off in my apartment. I need recommendations for a good cat litter that is perfume free, as little dust as possible and is not in pellet form. Any suggestions would be greatly appreciated.:nod:
