The item is nice but one chief issue.  It tips over way to  easy. The round base  offers no support in keeping it upright. My 5 yr old cat was playing on it and she was hit by it when it toppled. She is OK and I have since put a  20 lb weight on it, But sadly she isn't in a rush to get back to it. I will keep it and go to a hardware store and get some wood to modify it.  She really did like it at first  but buyer beware if you  have a bigger  cat or a really active one this is not the item for you  unless you  secure it somehow.
