Simple Solution Training Pads are 100% more absorbent than economy pads with an absorbent core that draws in wetness to prevent runoff and messy tracking. They guard against odors by inhibiting the growth of microorganisms. The five-layer construction uses advanced polymer technology to trap more urine for repeat use or for larger-breed pets. A powerful built-in attractant helps accelerate training time. Simple Solution Training Pads have a plastic backing and edging to help protect floors and are built with a rip-proof construction to prevent shredding and destruction.
