EziLock Odour Natural Mineral Zeolite Pellets are specifically designed to be used with the EziLock Odour Dual Layer Cat Litter System. These pellets are made from naturally occurring minerals and have micro pores that help to dehydrate moisture while allowing liquid to pass through to the absorbent pad below, thus reducing the need to clean up wet clumps of cat litter. They also lock in odours, making them ideal for use in a single-cat home for up to a month. These pellets are chemical-free, 99% dust-free, and low-tracking, making them a great choice for pet owners looking for an eco-friendly and low-maintenance option.
