My kitten absolutely loves this cat tree!!! It was easy to assemble.  One of the top pedestals is secured tightly, but wobbles.  My kitten is a little killer and hunter and they did not make this product tough enough for her.  Within the first few hours she had this tree, she ripped one of the secured mice off!!! My only complaint is about the delivery.  First I was told it would arrive on Friday, then it was suppose to be here on Wednesday.  It arrived on Friday but was not brought to my door, but left out in the carport.  It clearly states on the box that it required a minimum of 2 people to lift.  I live alone so I struggled to get this into my house! Otherwise-love the product.
