Making a pet tunnel is as easy as repurposing a cardboard box. Has your cat or dog seemed bored in the house lately? You don't need to spend a fortune on state-of-the-art pet toys. If you have several cartons, you can easily get your pet to have the Cat Scratching Tunnel. You don't need to impress your cat with a fancy or elaborate Cat Scratching Tunnel. You can do something as simple as cutting two cat-sized holes in the sides of the cardboard box so they can crawl in the Cat Scratching Tunnel.

To give your cat more room to explore, connect several Cat Scratching Tunnels end-to-end, making sure the holes on each are connected. Glue the boxes together to make sure they stay in place while the cat plays.
Play tunnels for dogs really don't need to be much different from cats, but if you have a larger dog, you can remove the top and bottom of the cardboard box and place them on the sides instead of cutting the small holes. Connect multiple boxes so the dog has a longer Cat Scratching Tunnel to go through.
Through the above introduction and analysis of how to get your cat to gain the Cat Scratching Tunnel, hope it helps you.
