Bought this for my cat last Christmas. Put it on a radiator downstairs on christmas day, she just wasn't interested. So took it up to our bedroom that night and put it on the radiator under the window that she watches the world from. The next day I couldn't get her out of it!
She considers this to be her day bed, enjoys waiting for us to get up in the mornings, it's at a good height for staring!
It is the best thing I've ever bought for her, a year later and it is still her favourite.
