litter box with pee pad

Several models include a non-slip or removable litter mat or a built-in litter-trapping pad (often called a pee or urine pad) to catch stray litter and reduce tracking around the box.

Enclosures and cabinets commonly use built-in litter-trapping mats, ventilation holes to improve airflow, waterproof/wipe-clean surfaces, and centralized entryways to contain litter and keep the box out of sight.

Many automatic boxes include presence-detection systems—such as weight, pressure, or infrared sensors—that detect a cat in real time and pause or delay cleaning until the cat exits.

Urine pads absorb or lock in urine to reduce moisture and ammonia smells. Pellet materials (for example, zeolite) and ion-based approaches are used in some systems to neutralize or trap odor-causing molecules at the source.

Mats and litter-trapping pads catch stray litter as cats exit the box, helping keep floors cleaner. Product listings and reviews commonly report reduced tracking when such mats or pads are used.
