It took only a couple of days for my cats to figure out how this is supposed to work. They love the little cardboard perches but it didn't last long at all before they decided that there was nothing good inside. I had hoped by buying them something that looked interesting and wasn't totally made in China, which so many products are. Sadly after about six months their attention has shifted from the scratching area upstairs to throwing up on the carpets.
