Highly recommended, especially for indoor cats
I bought this a few months ago for my house cat (~2 years old at the time): she took to it immediately and has not left it alone for long since - I wish I'd bought one the day I adopted her.
She's up and down it when having a mad run around on her own, it is an interesting part of the terrain when running around with me and the things on strings, she scratches it rather than anything else in the room, and the bowl is one of her favourite places to nap.
Considering how small some fancy scratching posts are that cost the same £70, and the fact that it looks like it will last a good few years of constant use, this tree is very good value for money IMO.
If you have indoor-only cats you must get a tree of some sort, trust me: they will make good use of it, and this one is a good choice.
