The Catit Airsift Jumbo Hooded Cat Litter Pan provides privacy while keeping the litter (sold separately) inside the pan. The large hood lifts up for easy access for cleaning, while the built-in bag anchor helps keep the bag (sold separately) open and frees hands for scooping. The carbon-impregnated filter effectively traps and removes litter box odors, and a generously sized door makes it easy for your furbaby to get into and out of the box. This litter pan is purr-fect for multi-cat homes. Replacement carbon filters are sold separately so you can keep it working at its best.
