Any suggestions to get my cat to stop ripping wallpaper. She only seems to do it at night, never seen her scratching it but she’s wrecking it mainly the hall and stairs, I keep pasting over it and have added cat repellant to the paste but it’s not stopped her. I have 3 scratching posts that she uses too. I have pinned tin foil to the walls which has stopped her but it looks a bit weird!
