I have the most finicky cat EVER! He only eats one kind of food, well only drink out of one certain bowl and absolutely won't try a different litter. I purchased this hoping and praying he would try this, as it sounded like am excellent product. I kept one of his litter boxes filled with his preferred brand and filled another with Pet Safe. After an hour he went to investigate the new litter. To my surprise he actually did his duty in the new litter! No smell, no dust. It's been three days and he hasn't goneback to his old litter once! It's a miracle!
