O…m…g!!! I ♥️♥️♥️ this cat tree!!! It comes partially put together and I only had to attach 4 pieces, and no tools required AND I put this together in under 5 minutes. It’s very well constructed too!!!  I’d post a picture, but my nosey one hasn’t checked it out yet, but she will!I ordered a tree from another place, and my 14 lb. boy would have broken it over time. This is so roomy for my 3 for sure.
