Actually the Fummel board deserves 5 stars! After I'm gone for fifteen minutes with fine sandpaper over it, it has become the favorite toy of our cats. Normally one must not necessarily reworked in injection molded articles, but in children and animals should after all put special care in the products of the day. And just as the Fummel board from the packaging is, you can not set before cats, partly there were really long razor-sharp ridges that I had to remove.
Therefore, the product is the way it is delivered not worth a star.
