My two BKH Kitten got the scratch board when they were approximately 16 weeks old and unfortunately so started to scratch sometimes the wallpaper. When I pulled out this scratching board and had a bit of the included catnip distributed on the wallpaper were totally uninteresting. You lie down on it like and above all, they scratch over and over again on the board.
Sure, the board dissolves and then you have distributed the paper crumbs around the scratching board, but if you sometimes directly out sucks the loose parts while vacuuming, which is actually no longer a problem.
