cardboard cat scratching post

I was fed up with my cats scratching the heck out of my living room sofa and loveseat, so I recently bought my adorable feline friends a cat scratching post made of cardboard, because a friend had suggested that I should buy this. Yeah right! The cats went to town on the cardboard post, and eventually, they were back at tearing the furniture to pieces. Cat scratching posts are great, just not in this material.
