My kitten took to this tree right away.  He knew instantly what to do with those scratch posts and he loves the little house.  I was looking for a tall tree with a narrow foot print so as to not take up much floor space. I found this!  It was better priced than the pet stores and found it to be more stable. Other reviewers had posted that their cat didn't use the top tier and neither did mine, even as he got older, so I unscrewed the top tier and the post from the house and placed it upside down in another room for a small scratch post. He loves it!
