I tried to pick what I thought would be the most substantial tree as I have a very large Manx cat. It is ok. Very shakey when my cat jumps up on it and the pieces are not really large enough for a 20 lb cat.  My cat still jumps up to the level I am feeding him on but the top perch is so small and shakey there is no way he is going there. The little round house is totally ignored as is the activity box at the bottom.  So I guess I would have to say "no " if you have a larger cat.   I'm not sure about the return policy but I would return it for another model if I could. I think it would be a plus if the designers came up with a line that would support a larger cat.
