I was very excited to receive the cat tree and as I was putting it together I noticed one of the pads would not line up with the posts.  It was the wrong part with the wrong holes.  So i took pics and sent it to the company and they sent me the correct pad with the correct holes. Its a nice tree but the 2 pads are a bit small for my full grown cat.  Its a good size for the kitten but he will grow soon.  But they still like to get on it. I wish the pads were larger.
