First I want to say it is well made & sturdy.  The issue for us is that it really is for a smaller cat. The platforms are not roomy & the top of it is more for sitting. The placement of the ladder really doesn't do anything for the cat so we left ours off.  I think kittens would love this tree but our boy, Arthur, is a larger boy & only part of him fits in the house at one time.  When Arthur was filing his complaints with us, one of the main ones was a lack of padding for soft places to sleep. :)
