Who does not so great quality demands on a scratching post, is well served with this at the price. Leidern are the trunks wrapped with a thin, about 5 mm thick sisal, which is severed quickly in joyful cat scratch. In order to ensure the stability of the tree, the Stäme and connections should be tightened. Unfortunately, even the ceiling attachment in the quality is not quite convincing. The threaded rod on the top stem is somewhat unstable and shaky, especially if the ceiling is higher than 2,40m. The threaded rod as well as the wing nuts tighten every now and then! What, however, I noticed: The Katz tree not report as much to chemistry. For me the product is however sufficient and the price (other require the same quality much more ...) I can the flaws well tolerated. By the way, he has not fallen over, I wonder if my two cats have him all day in fitting ... ;-)
