Cats are complicated creatures that somehow have a strange obsession with cardboard boxes. You can buy them the most expensive cat bed and they'll pick a random cardboard box over it in a heartbeat.
The problem is, they don't even care if the box fits or not, they will completely disregard that and try to squeeze in it or just casually lay over it. No one knows why cats do the things they do, but someday we might be able to get inside their heads and figure them out.
The cats in the photos below are just casually chilling in cardboard boxes and they look cuter than ever.
