Wrap (hide) the new Simplify Cat Scratching Tunnel and let cats find it on their own. If you don't have a chance to train your cat to use the Simplify Cat Scratching Tunnel, you can hide the cat's claw board and let the cat "find" a new scratching board by itself, which may be more fun (for cats).

If the cat discovers the Simplify Cat Scratching Tunnel by itself and "takes it as its own", then you don't have to worry about it anymore. Sometimes, competition between cats can interfere with scratching post use. If a cat is being chased away by another cat, make sure the cat that was being chased away has its own scratching post.
In a family with multiple cats, each cat has its own territory, and each cat likes a different place. It's like every cat doesn't like the Simplify Cat Scratching Tunnel used by other cats, they all want to have their own "personal" items.
Through the above introduction and analysis of how to use Simplify Cat Scratching Tunnel, hope it helps you.
