Even after assembly it was clear that this scratching post is not really stable. He also has the first days smelled something strange. Although the cat tree offers plenty of space, where lie the cats, play, or can play, but this is not readily at our hangovers possible. We have fixed this scratching post via metal brackets to the wall and only since our cat can jump without problems on the scratching post. Before, it would have been a wobbly! So for adult cats this is no wall fixing anything! For the price, however, the scratching post was fine and after 2 years still makes a good figure! Its material, it is fine and the Sisalrollen are still intact despite frequent use.
