Good sturdy tree, happy kitties
So far it looks like a fairly sturdy tree, which was the main reason I chose it. I have 5 cats, 3 of whom are both boisterous and large (5.5-6.5 kg). This tree has a large square base, and thick poles so it is hard to knock it over.
Some negative points: the covering material is quite thin, there were already torn and frayed bits on the first day. The posts had staples sticking out, causing scratching.
Also would have preferred all sisal posts, as I know the fabric covered ones won't last long.
