What is it with cats and cardboard boxes?

Cats and cardboard boxes have long been strange bedfellows. It’s no secret, cats have a strange affinity for cardboard boxes. But, what is it about a box that’s so fun? Why do they love sitting in boxes, and sleeping in boxes?

A study conducted at Utrecht University in the Netherlands points towards boxes providing relief from stress – they’re likely to feel safe and be left alone when hiding in a box. In the wild, a hiding place like this would be perfect to relax, safe from predators.

Another theory is that boxes helps keep cats warm. Cardboard boxes are generally layered and become great insulators that keep cats safe from drafts.
