I'm convinced all cats love it
I don't know what it is about cats and cardboard but this bed is a hit with every cat i know. We got it for ours on a recommendation and she loves it, my sisters 3 cats (and the 14 kittens she had at one point) love it and so do my parents-in-laws two cats.
They scratch it, they play in it, and they sleep in it.
The sad part is after 6 months of use, it is looking a little tired but we will be replacing when she's thoroughly ruined it.
