Discover new ways to play - The marble run is connected at both ends by magnets. After connecting, turn them over to create toys of different shapes. Magnets can also connect multiple components to form a giant tunnel for homes with multiple cats. Track and play - The package includes colorful balls that fit on the track. When the track is unfolded, the balls will not fall out no matter how your cat plays, so you don’t need to chase them around or search under the furniture. Durable, safe materials - The scratching board is made of corrugated cardboard for long-lasting use. It is CNC-cut for precise edges that will not hurt skin or pinch claws. It folds down easily to palm size for convenient storage. Satisfies natural scratching and protects your home - This board provides a healthy outlet for scratching while helping protect your furniture and blending with home decor. Use scenarios - Solo play: Your cat interacts with the magnet-connected marble run for engaging, independent play and problem-solving. - Multi-cat households: Connect multiple components to create a large tunnel that keeps several cats entertained at once. - Space-saving setup: Use the compact, palm-sized scratch board to save space and protect furniture in small living areas. Note: All features align with the original product functions, including magnet connections, included colorful balls, CNC-cut edges, and the emphasis on safe, durable cardboard construction.
