The Trixie Crabboard cardboard with 2 balls is an original scratching board that offers extra appeal and fun. This way, your cat is more likely to scratch the scratching board instead of your furniture. The scratching board has a triangular shape and an attractive wood look. The shelf is made of cardboard infused with catnip. Inside the scratching board, there is a track where two balls are placed, allowing your cat to play by batting them back and forth through the shape. Trixie combines scratching with play, ensuring that your cat won't get bored.
