Cats love it.
Both my cats have taken to it immediately, in fact they were both in it before the beds were even sorted. It's good quality, sturdy and well made. My only gripe (and the reason for 4 stars) is because I feel the top wooden disc looks a bit unfinished. I think I'll maybe paint it cream, and it does look a little messy with the removable bed the way it is. It would look nicer if the material for the bed covered the wooden disc. This is a design flaw that I will need to rectify some how.
