My cat absolutely loves every level, which is a relief because for the first month or so, she seemed to WANT to explore the upper levels, but she really couldnt access them. Theres no stable platform on the third level, so it was hard for her to jump to the fourth level. I guess shes become more confident with the tree over time and now has no issue whatsoever hopping up and down any level of the tree. She loves every level of this tree and I couldnt be happier! Its very cute, cozy and sturdy. The material is great too. Dont be alarmed if your cat takes a little bit of time to get comfortable with using the upper levels at first.
