The generous 36" x 30" surface of the Heavy Duty Litter Mat provides floor coverage well beyond the edges of the cat litter box – preventing litter from tracking throughout the home while protecting flooring from grit and accidents. Mat is tough, durable, fade resistant and repels liquids. Made in the USA from marine grade carpeting.
