We purchased this item in the hopes that it would be adequate for a mom cat and her four kittens.  Let me tell you, I could not be happier with how they have all responded to and taken over their new tree.  The quality of the item is better than most I looked at in the big name stores.  I can say that I do wish the little box rooms are a tad small.  The adult cat has to pretty much butter her butt to fit inside.  (but she does seem to get comfortable enough to sleep)  All four of the 4week old kittens can fit in one box with room to spare.  (these are all stray cats that have taken over my back porch)  The kittens climb and play and sleep on this tree.  I am more than pleased with the tree and if ever needed I will definitely return to this site to purchase another. Have a wonderful day. Cheryl
