Why Do Cats Like Boxes?
"Cats like boxes because they are cryptic animals; they like to hide," Stephen Zawistowski, science adviser for the American Society for the Prevention of Cruelty to Animals, told Business Insider. "And a box gives them a place of safety and security."
While inside a box, cats feel that they cannot be snuck up on from behind or the side — anything that wants to approach them must come directly into their field of vision. In effect, such hiding spaces allow them to watch the world around them without being seen.
