As my headline indicates I have mixed feelings about this product. I surprised my wife with the purchase of two Cat Condo/Gyms. Assembling was the negative. Copy it's competitor and use alphabet stickers on the product. Saves a lot of frustration. Positives, it is large and with a multiple cat household it's fun to watch all of them using this. My Bengal loves the multi layers. She can be found resting on the bottom tier or batting around the toy at the top. Our other felines each have their respective favorite spot.
