I've had quite a few of these cat activity centres in the past, but wanted to buy a really big new one. I did a lot of internet searching and this seemed to be the best there was, although I was a little suspicious about the price, which seemed quite cheap (just under £66 incl P&P) considering the price of these things in pet shops.
However I am pleased to say this is absolutely the best cat activity centre I have ever seen, let alone owned. It is superbly built and absolutely enormous, my cat has so many different places to sleep, she loves the two round thingys, but also likes going into the little 'houses'. She also loves climbing up it very quickly.
There is one downside, and that is the time you spend building it. The instructions are really poor, they consisted of a kind of skeleton drawing of the centre with the screws showing how to fit everything together, and one sentence: Start from the bottom up. I am pretty good at putting things like this together, but this really was a nightmare. If you get one, you will see what I mean. (And in fact there were 3 screws missing from the box but the German company I bought this from were absolutely fantastic at very quickly sending through the missing parts.)
But despite the instructions, it really is a fantastic item. Yes you will spend many hours trying to build the thing, but it is completely worth it, an absolutely superb product.
