Trying to help out SDD who is in rented accomodation. Naughty mogs are scratching the wallpaper on the stairs etc, and apart from re doing the wallpaper every week is there anything that would make it more difficult to scratch/or not show, that wouldn't be difficult to change back at the end of the tenancy? I suspect the Feliway spray would damage wallpaper, and she has the feliway plug in which hasn't made a difference. Is it just impossible to stop, and wallpapering is the only viable thing? I'm hoping you cat people can come up with a solution that I haven't thought of! TIA.
