My cats are unsure
This is taller than my wardrobe and our cats are too scared to climb it lol. They love the plush beds and will happily sleep there as long as we put them in it - we make sure there's a comfortable way to get down though, as it really is high and easy for them to land badly. We have had issues trying to screw it to the wall, but it's secure enough that it doesn't wobble (even with two british shorthairs on it), though it is braced beside our wardrobe.
