By using chemicals to camouflage foul odors is hazardous to your cat's health and will only increase the odor build-up. Catit Magic Blue successfully reduces hazardous ammonia gases, which is the most irritating gas found in cat urine. The cartridge is a perfect fit for every litter box! It includes the reusable cartridge, dual sided self adhesive pad and 2 refill ammonia reducing filter pads (1 month supply) that help filter the cat's litter box.

Place the two pads inside the cartridge. Remove one side of the dual sided self adhesive pad and place it on the back of the cartridge. Then remove the other side of the self adhesive pad and attach the cartridge to the litter box's interior.
