Very easy to put together. It's adorable and my cat loves it.

I have owned this for several years and all of my foster kittens love it. BUT BUT BUT The upright piece is way too close to the curved scratching surface and kittens have gotten caught in the space and not able to free themselves. This is hazardous! I took a drill and moved the hole where the upright is attached to the base. Now it is much safer. Do not use unsupervised unless you do this. It is not safe.

Kittens bit the strings within an hour all the balls were off. Sucks.

My little guys were only 6-1/2 weeks old when I purchased this. It took them a couple days to figure it out, but when they did it became one of their favorite toys. They play on it individually and together, and I know it will keep them entertained for quite a while. Great entertainment in a small space. Really glad I purchased it!

I did not look at the size correctly and I thought it was much taller. My cat does not play with it at all. Maybe another cat would enjoy it.

My cats Love scratching and playing on Scratching Tower. They are entertained off and on continually every day. A must have for cat lovers!

Kittens love it looks good quality but they chewed off the balls

This toy is for a smaller sized cat which I could see from the measurements but which I had hoped would not make a difference. Both of the boys are interested in batting the fluffy balls but are too large to fit easily under the arch. Thus far there has been no scratching nor climbing. (They have lots of places in the house to climb much higher.) One cat has been more intrigued by the box in which the toy arrived. I feel that I might have been somewhat remiss in providing a variety of play opportunities for these 15 lb brothers over the years so I have decided to slowly add items in which there might be some interest. If a few minutes of play per day are all that happen, I'm satisfied.
