This is a great product! Well made for the price. The modern design is quite lovely. It comes with easy to understand directions, and set up takes no more than 5 minutes. As soon as I finished, my cat jumped right into it. My boy is 8.5lbs with a slim build and is able to sit comfortably, however a larger cat may have problems. I have included a full body pic of my baby outside of the condo for size comparisons.
