This is WONDERFUL...  No doubt if my two cats were able to speak they would most definitely say that they absolutely LOVE this cat house.  :)  it was easy to assemble (I did it alone in about 45 minutes.  The only minor problem is that it was missing a bolt and the bolt wasn't your average bolt to pick up at the hardware store however Wayfair stepped up to the plate and sent me the hardware required.  Thank you Wayfair.  My cats use their house daily from jumping up and down the tree either independently or chasing each other as well as sleep on it and play on it as I attached toys to it.  I ha e two artificial five feet trees behind it as you can see in the pic.  Thanks again Wayfair!
