Semi-enclosed design: Provides your cat with a sense of security and privacy while using the litter box, encouraging regular use. High edges: The raised edges effectively prevent litter or litter from splashing out of the box as your cat digs, keeping the surrounding area clean and reducing the need for frequent cleaning. Odor filter: It comes with a built-in filter (usually carbon) that helps absorb and neutralize unpleasant odors emitted by litter, leaving your home fresh and odor-free.
