Love love love. Just got yesterday. The directions had 2 points where you can easily mess up so I feel like I built this twice which was frustrating but it turned out great. Quality wise I would rate it 8/10 but it gets the job done and my cats love it. We ended up putting their stuff on top and now they nap there. I’m really hoping this holds in the odor since we are in a small apartment. I purchased charcoal bags to assist as well. I wish it was a little taller but like I said, it gets the job done.
