This was super easy to assemble. I assembled it myself in about 15 minutes. It might have gone faster, but by cat was exploring it as I was building it. Whether it’s scratching on the posts, lounging on one of the levels, or getting some private time in a hidey hole, this heavy duty cat tree is well worth it! If I had a bigger house, I would be getting another one. Whether it’s for the feline in your life or a special gift for that cat person you are trying to impress, this is sure to be a winner.
