Paws and Pups collapsible cubes, tunnels and play homes are designed to give youÕre cat a fun interactive toy that they can explore, hide and play in. Cats love to hide in tunnels because they offer a safe area where they can observe and not be seen. This helps them feel comfortable and secure. Our tunnel has a clever collapsible design that makes it compact and easy to fold up and store when not being used. Our tunnels also have a tassel ball that dangles at one entrance of the tunnel, allowing your cat to play when they donÕt feel like hiding anymore. Our tunnels also have attachable clips at the end, so you can join tunnels together or attach them to our cat cube house.
