Unstable even for small kittens
I bought this for my ~7kg cat, and he wasn't comfortable using it because the thing would start to tremble when he climbed it. Now I have two small kittens of ~1-2kg each, all the screws are tightened, but the thing is still shaking! Weak material and poor construction. The fact that Zooplus advertises this as a Top Seller sadly undermines my trust in Zooplus.
