The design looks pretty, but in practice it is unbalanced, and my 9 lb. cat won't go on the top tier because it shakes too much, even with the 20 lbs of weights I put on the base. She loves the sisal for scratching posts, but is only using the ones on the base. The little house ought to be on the top tier, and larger - it is barely big enough for a kitten. Nice compact packaging, It would have been a good price for a sturdy tree, but not for this one.
