I ordered this one, but received the wrong cat condo and although Customer Service quickly reordered the correct one to be sent, I am having to wait three weeks to receive return instructions or notice to donate or dispose of the incorrect one.  Very disappointing, since I do not have the space in my living room to store this big box, especially when the correct item arrives.  Not sure why it takes three weeks, but I doubt I will order any additional items in the future.
