The product itself is really great. High quality, easy set up, appearance is nice - but know it is for small to medium sized cats.  I have a cat approximately 10-12 pounds, big not a long hair, so getting into the cubby hole wasn't his favorite because he is so big and jumping up to sit on the top platform made the tree shake.  This was nothing to do with the product just his size.  I do recommend this product with the knowledge of the size/weight of your cat.  Thanks!
