I have the scratching post ordered on Saturday and today, so Tuesday, he has already been delivered. I have set up the tree in one hour alone. The instructions were clear and detailed. The cat tree looks totally great. I have a big, fat cat and the tree is super. After I had read that the top boards be small, I have the highest board replaced by an old, larger Kratzbaum board. But my fat cat rather lies on the small board. Yes, he is sure, though it depends on what the know, but he seems nice to find it. I opted for the tree because the lower house is longer. And my cat has the lower house immediately taken into possession. So the perfect size. Somewhat surprised, I was on the design principle of the houses, but the idea makes me happy. There are two boards up and down and by introducing small "post" the house is stabilized. The walls are made of fabric. Something I doubt that will keep the scratch columns long. The sisal is quite thin. But still for the price I am really happy. Especially for older cats, this tree is suitable because the conductors connect each floor and the top boards are not so far apart. I hope my description has helped you.
