Nicole Dew mineral sand is carefully selected from high-quality sodium-based mineral sand. It forms flying saucer-shaped clumps in 2 seconds, has strong water absorption, and the clumps are stable. It can be cleaned up with one shovel. The scientific gold mix ratio is 4 in 1, with additional activated carbon and zeolite added, providing multiple deodorizations to protect the odor of the home environment. Additional mineral salt is added to help absorb odors, moisture-absorb and inhibit bacteria. The raw materials are free of fragrance and powder, protecting and harming the sensitive sense of smell of cats.
