Drainage System – Pet-friendly artificial turf is designed with superior drainage capabilities to quickly remove urine and prevent odor buildup. These drainage holes allow liquid waste to pass through easily, keeping the turf dry and sanitary. Odor Control Features – Pet turf is often infused with antimicrobial and odor-neutralizing properties, such as infill made from zeolite or silica sand. It helps to break down and absorb ammonia from urine.
