My cats absolutely just love their new cat condo. It is huge with plenty of play space. It took me 2-3 hours to assemble this. The key is to sort and set everything aside first before trying to assemble it. The picture was not very clear regarding which piece is a scratch post and which is not. You just have to figure it out from looking at the picture of the fully assembled condo. It would be much easier to use words to describe those pieces. This would be a great help and a time saver for purchasers. The purchase was delivered on time faster than what promised, and best of all, every pieces were there and complete. Thank you,
