Was looking at buying a cat condo/tower, but when I seen the prices of $ 1,000 and up, decided to build one, Three weeks later, I had close to $ 500 in it, but its built solid and will not fall apart. Over 800 feet of the rope on it. Was worth the time and effort, they live on it and I need to start replacing some of the carpet from wear. One of my neighbors had seen be building it and when completed, he offered me $ 600, I looked at him like he was a fool. LOL
