I live in Canada and couldn't find anything near this big for anywhere near this price in stores. [...] My cat couldn't even wait for me to finish putting it together before she was all over it.  She LOVES it.  Like others have mentioned, my cat doesn't use the hammock (even though I was sure she would).  But she loves the top two tiers and the 'house'.  It was very easy to put together - I put it together at 10:00 at night easily.  I do not have it up against a wall because I want it in the window because that's where my cat loves to be, so it is somewhat wobbly without the support, but my cat is still quite small so at this point I don't think it's a problem.  As she gets bigger I might have to rethink that though.  I was originally looking for a carpet covered one, but the faux fur on this one seems sturdy and she is able to grip it with her claws well.I keep saying to everyone that this was one of the best buys I've made.  Strongly recommend.
