Feline litter box uses advanced odor technology to eliminate your cat's waste odors. Covered design combines a whisper quiet 6-volt fan with foam pre-filter and an activated charcoal and zeolite filter to control litter box odors, trap dust, and reduce air particles. Unique filter indicator lights visually indicate when the filters need to be changed (approximately every 6-8 weeks). Features a clear plastic roll-top lid that offers your cat privacy and reduces scatter; however, the lid easily rolls back to offer total access to litter pan area and simplify cleaning. Includes a contoured litter scoop that allows scooping in the corners of the litter box. Also includes two sets of filters. Scoop rests in a convenient holder on the back of the litter box. Holder is slotted to allow litter to fall back into the litter pan. Features an AC adaptor with 12-ft power cord.
