This tall, stable faux-fur condo was exactly the right choice for our active cats, both within the 8-12 pound range. The house and perches are large enough for both to enjoy and the multiple levels provide plenty of climbing and lounging opportunities. One has already discovered the many scratching locations provided by the tightly wrapped sisal pillars. The design and engineering of the system is excellent--clear instructions, quality hardware, minimal time and tools needed. The only drawback (noted by others) is the ladder, which is positioned in a way that prevents easy access going up and was rarely used, so we removed it. We also didn't attach the toys on stretchy string; too easy to chew off and swallow. Cut the string off and use the balls as throw & chase toys. Great price for a fine product!
