My cat absolutely loved this, so much that he started playing on it before I put it fully together! He is about 3 years and average weight for a big cat.
The instructions for putting it together weren't the best, but I soon figured them out.
Absolutely worth the money, and very happy with the product. The delivery was also incredibly fast (came 2 days after ordering).
Would have given it 5 stars if it wasn't for the instructions.
