I'll be returning mine. There are 2 issues: 1) it is very wobbly so 2 of my cats tried it once and then never again, and 2) difficult for a cat to get from the first tier to the middle tier because their widths are almost the same and a cat would have to go out and over as if it were an overhang and it's too awkward. Even my agile and athletic kitten lost interest quickly and gave up. The last thing I'll say is I will buy a more expensive cat tree that has carpet covering instead of the cheesy faux fur. No offense to the makers, it's just my preference.
