The privacy part of the story
Cats Protection describes a box as a private place to rest away from noise and other activity. That is a useful way to understand the appeal without treating a cat as a puzzle to solve. A cat choosing a box does not tell us everything about its emotions or its household. We have not inspected the place, the material or the animal, and this guide does not label a particular arrangement safe.
Cardboard has physical properties
The same article discusses cardboard insulation and the warm, enclosed feeling of a box. These are general explanations for an attraction to cardboard. They are not temperature targets, advice to confine an animal, instructions to add heat or a comparison of commercial products. We do not calculate insulation or recommend a size based on a photo. A material explanation and an individual choice should remain separate.
Play is another context
Cats Protection also discusses climbing, hiding and playing around boxes. That does not mean a person needs to initiate a game or disturb a resting cat. This site does not prescribe an enrichment session or build a structure. Its narrower purpose is to help readers see that resting, exploring and playing are different contexts, and that a single box photograph cannot establish which explanation applies.
