Well, the platforms are too tiny for normal size cats to enjoy. They'd roll off if they tried to get comfortable on one.  The box is the only part wide enough for a 10 lb cat. It should be sold as a kitten or small cat (under 10 lbs) climber. We would return this one if there weren't so many holes in the wall from the mounting process.   It's just not what we expected from the pictures on Wayfair.
