A heavy-duty scratching board is a reinforced surface designed specifically for cats to scratch, stretch, and maintain their claws. Unlike flimsy or temporary scratchers, heavy-duty boards are made to endure vigorous use and repeated wear. Common materials include compressed cardboard, sisal rope, and woven fabrics—all chosen for durability and claw satisfaction. https://www.myrainbowpets.com.au/collections/cat-scratchers
