Pretty easy to put together, all done with an allen wrench. Put it facing a window so my 2 cats can watch the birds and rabbits. They were leery at first but I sprayed some liquid catnip on it and it peaked their curiosity. I don't see them on it too much because when I am home they always want to be in my lap but I see paw marks on it so I am sure it is being used when I am at work.
