I bought this beautifully well made cat tree for my sons little 10 week old kitties! I thought that it would be a good 3-4 months before they would be brave enough to try and climb this 6 foot tree! Boy, was I wrong! They started climbing all over it within the first few days! Mind you, these are tiny little 10 week old kitties! They really love it and so does my son! It took my husband and I about 1&1/2 hours to put it together. I love that it has many sisal posts for scratching and also the soft warmth of the fur over all other parts! If you have a lot of space in your room, this tree is the one. They also love to snuggle in the hammock! Get it, you won't regret it! Thank-you again Wayfair for this wonderful product!
