The structure of the scratching post will only work if you do not comply with the instructions, otherwise it is really too complicated. Mounting okay so far. Price is okay, but I've already bought cheaper Scratching Post, but are then at least stable on the floor. Well, that this is a Corner Scratching here, because one can put him well into a corner and when the cat jumps on it, then he cant not at least. To make it free tzu in the room, it is unfortunately too shaky. Our 2 Fellnasen have the tree assumed to be equal. 3 stars I admit, because he looks nice, the cats are stimulated here to hide in the cave or to climb and do our well However, there are trigger in the stability and the substance which is very thin. Because our tree but in the computer room is in a corner, it is okay for us.
