This is my first cat tree. I wanted something sturdy with large enough levels to accommodate my two one year cats. I liked that the parts had letter labels and picture directions were easy enough to follow except for enclosed section which was hard to line the dowels up inside and could be bigger. Wish it had two top bunks or it was larger as that’s my cats favorite level but they don’t fit there comfortably together. Hammock is nice and big and often one will lay there if other is on the top. They also like the dangling ball.
