UltraBlok Underpads provide reliable medium to high absorbency with a thermo-bonded polypropylene non-woven top layer and thick, absorbent fluff core. A waterproof polyethylene film helps prevent leakage, creating an effective barrier against urine, blood, and other fluids. Use over bed linen, furniture, and equipment to protect surfaces at home or in veterinary settings—great under a dog bed or cat bed to keep areas cleaner. Fast wicking action helps keep skin dry, and the disposable design makes clean-up quick and easy.
