The model was downloaded from here https://thangs.com/designer/Catalpine/3d-model/HOUSE%20FOR%20CAT%20TAO%20LOW%20POLY%20V2%20-%20Follow%20us%3A%20https%3A%2F%2Flinktr.ee%2Fcatalpine-991358 so if you can support the creator(s?) please do so :)
As an alternative, I also made one for my other cat using this freely available model: https://www.thingiverse.com/thing:4817590
