This product is awesome! I have a nine year old inside cat that is on the chubby side. He was unsure about the tree at first, but then I put up the dangling toys and he is on it all the time! I put some catnip on it as well, and he loves to sleep on it now too.

The only con is that no matter how tight you screw in everything, it is still a bit wobbly, even when placed in a corner. It has not fallen though, so this is not really a problem.
