Review on Petlinks 49900 Hanging Cat Scratchers by Sidewinders Murphy

My only real gripe with this item is that it's impossible to close the door when it's on the knob. which kind misses the purpose why we bought it. Our cat will scrape the shit out of our door every night if we lock it in our bedroom. If we let him into our bedroom, he'll jump in his sleep and knock everything over. I'm attaching a photo of the perpetrator. I sincerely wish for that scratch as I smack our cat Jefferson on the head every time he tries to scratch something. It would be helpful.
