This extends to being placed into a closed litter box cabinet with only one opening. Many cats will refuse to enter or will enter but turn around and peer out looking for a threat. We eliminated that fear by placing two openings (one on either side) in our cabinet so that cats feel a sense of comfort and security. These two openings also create a fresh air flow which help eliminate odors. Choosing a quality cat litter is also very important. We recommend The Worlds Best Cat Litter inches found in major pet stores. Ours comes completely assembled. All inside joints are caulked and the entire cabinet is water proofed. Cup hooks are added for scoop and odor removing product. Everything you need is found within the cabinet.Made in the USA.Note: White, Green or Blue finishes are special order and require 4-6 weeks to be custom made. .
