I'm still using it, second winter that my outdoor (mostly) cat has used this cage at night and she goes straight to it when she knows it's going to be cold, and loves it!  Don't panic at all the pieces, just get familiar with them, lay them out, and it really isn't difficult to put together.  Once together it's very sturdy, and I don't have to worry about my cat wandering around or waking me up.  This is a large cage and certainly two cats would be fine in it. I absolutely love it, don't regret for one moment spending the money on it - best buy ever!
