Query: Pretty good, but expensive and held together with glue.

This is actually a pretty good product. I purchased it because the height of each step what appropriate for my cat. Also, it looked nicer than some of the plastic ones, and has the carpet on the steps. However, i was very surprised to find that it is held together only with glue, no screws. I also find it to be quite expensive. If I had a bit more length to place it, I would have certainly purchased something just as effective and much less expensive
