My cats loved this immediately! Super easy to put together, really clear instructions, well packaged and delivered really promptly, but most importantly my two very fussy sphynx cats love it. My kitten loves the puzzle at the base, and my older sphynx loves stretching his back when using the post, it's tall and sturdy enough to handle both of them playing with it at the same time. 10/10! I cannot recommend this product enough.
